I am deploying a laravel installation in AWS, everything runs perfectly when I allow it to recieve all inbound traffic (EC2>Network&Security>Security Groups>Edit inbound rules.), if I turn off inbound traffic and limit it to an IP it doesnt load the webpage it gives me this error:
PDO Exception SQLSTATE[HY000] [2002] Connection timed out
However for security reasons I dont want this setup like this, I dont want anyone being able to even try to reach my webapp. Everything is being hosted in AWS, I dont have any external entities, its running in RDS and EC2. I added en elastic IP address and whitelisted it, but that didnt work either. I followed every step in this tutorial : http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/php-laravel-tutorial.html#php-laravel-tutorial-generate
Environmental variables are working as well as dependencies, well.. pretty much everything unless I restrict inbound traffic as I mentioned.
How do I whitelist AWS own instance then to make this work with better security?
Thank you!
I think part of this answer is what you may be looking for.
You should enable inbound access from the EC2 security group associated with your EC2 instance, instead of the EC2 IP address.
More than just adding an elastic IP address to your AWS instance you need to do two more things.
Assign the elastic IP to your AWS instance ( yes is not the same as just adding it to the instance, you must specify )
White list the internal IP that it generates once you link it to your app.

I have a MERN application with the frontend hosted on Netlify. I currently have the backend hosted at onrender.com. However this is quite slow and so was looking for something with faster load rates.
I have set up an EC2 instance on AWS and it is much faster, but I am struggling to enable HTTPS traffic.
The current setup:
EC2 instance set up and backend running. (I have ran it locally over http and it works fine).
AWS: security groups enabled https
The issue is that when I try to connect over https, it does not work.
I have tried various things including the ACM certificates (I have a certificate for my domain), creating load balancers that would direct to my instance, but I don't seem to succeeding. Admittedly, I don't fully understand what exactly I need to do here.
The outcome I want is to simply interact with the backend, which is on an AWS ubuntu instance, from my frontend over https.
Any help would be greatly appreciated.
if you are going the Load Balancer way, should be fairly simple.
Yes, it is a good idea to use ACM to provision Certificate for you.
Make sure that the Security Groups are well configured
In your case the Load Balancer should accept traffic from port 80 and 443
The Instance security group should be open where you have configured the instance to listen, it depends on your impmenetation
In the target group make sure that you have configured the target port correctly (that is the ec2 open port, where recieves traffic), also make sure that the health check is configured correctly.
I attached a quick summary how this little architecture should look like
I have been trying to troubleshoot some connection issues, and I'm struggling with a relatively simple setup.
On my (relatively new) AWS account, I create a new Application Load balancer. I configure it in the following way:
Internet facing
Use the default VPC that came with the account
Across all availability zones
Uses default security group for VPC
Listens on HTTP:80 and returns a fixed response (status 404)
When I then try and use the new dns name assigned, it just hangs. When using curl -v I can see it says:
Trying :80
dig also responds with 3 IPs (I'm assuming for the different zones).
It feels like I'm missing something obvious, but I'm struggling to find it myself.
Can anyone see what I may be missing?
Can you please share a print screen of the default security group and LB configuration?
I am almost sure that the default security group has opened ALL inbound traffic but only for itself (security group).
I have been looking for help with this problem, and the answers just say to add inbound rules to the security group. Well, I have done those and I am still unable to access my website from the public DNS (just putting that into the url box and navigating to it). There are multiple port 22 inbound rules for the people accessing my server, and the outbound rule is just "All traffic".
I've had this problem running Wordpress on EC2 instances. Things I'd try:
Access the instance via ssh. Check out https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/AccessingInstancesLinux.html
If you're accessing through ssh, maybe it's because your disk is full. To check this you can run df -h on your Amazon EC2 server.
I tried accessing my newly setup AWS EC2 Instance and I had this same issue, I later realised I was accessing the public DNS via HTTPS which had not been set up. when I changed the url to use HTTP it worked. Ensure to configure HTTP in the security group.
I've been using AWS for a few months without any problem. But from yesterday, I can't access the website. When I ping the IP (52.24.23.108) it displays request time out. Server's status is okay - that I checked from AWS console. Isn't it a network problem of Amazon Webservices?
You need to enable the specified network traffic type (ICMP) through your security groups for your instance. You can do this by choosing Security Groups > select your security group and choose Edit Inbound Rules
Choose "ICMP" from the dropdown and source (* if you want it from everywhere) then Add Rule
PINGs should work!
A couple things could cause this, most likely you provisioned the instance with a public IP, by NOT a n elastic IP. If you had a server restart, either by your doing or by AWS, then your public IP would be dropped. If you did use a elastic IP, then look at your security group to see if you allow icmp still or if the security group changed.
Another cause may be if a server level firewall had been disabled in the past, but if your server went through a restart it may have started again. What base OS are you using?
I've read a lot of questions already posted on this topic but none seem to provide an answer that helps, so forgive me for the duplicate post if I missed one...
I setup an elastic beanstalk single instance application. I then ensure'd the EC2 instance that it spawned had a security group to allow port 80 incoming requests. I then created an elastic ip and associated the EC2 instance with the ip, but neither the public dns or the elastic ip will respond to http requests.
Any ideas why this might be an issue for me?
In my case the problem was, even though I'd associated my elastic IP to my instance and created firewall rules in new security groups to provide access, I hadn't associated my new security groups with my instance. To fix this, I used the Change Security Groups menu from my Instances screen:
This caused the following popup to appear, where, sure enough, my new security groups existed but weren't associated with my instance:
After I (1) checked the appropriate boxes and (2) clicked on Assign Security Groups, all was well.
In classic-EC2 scenario:
Make sure port 80 is allowed in your AWS security group.
Make sure port 80 is allowed in local operating based firewall on your system. OR disable the local firewall for the time being to narrow down the issue.
Make sure that your application is indeed listening on port 80. You can check this by running telnet 127.0.0.1 80.
If above 3 points are satisfied, I don't see a reason why you are not able to access your application on port 80.
Let us know in case you are using VPC and not classic-EC2.
BTW, when you attach elastic IP, the instance will drop the public DNS that it had earlier. So now you should work with elastic IP only.
I have had a case where the elastic IP address was itself not responding on a specific port number. When I associated the instance with a different elastic IP, everything worked fine. So I resolved the issue by allocating a new elastic IP address. Root cause: Amazon evidently does not have an effective internal process for validating the integrity of an elastic IP. Obviously that's a tall order considering the things outside their control that can happen, with denial of service attacks and etc.
It cost me a day of doing progressive isolation to get to this, which I would have never otherwise suspected.
Any chance there is also a firewall running on the machine? I know in windows I usually need to open the port on the windows firewall AND on amazon's security.
