Openssl Error Messages: Error:0A000126: Ssl Routines: :Unexpected Eof While Reading

This error manifests not only with PHP but in a broad variety of contexts, so I write a generic answer here. The other answers address the issue by upgrading software that have implemented the solution already upstream. The reasons and background is explained here. Most software linking OpenSSL have tickets where they introduce support for the new openssl behaviour, e.g. 1, 2, 3. Currently, in Ubuntu 22.04 LTS curl is version 7.81.0, and fails in case of unexpected EOF with OpenSSL 3.0.x. The latest curl is 7.88.1, and apparently resolved the issue, though I could not find the exact commit or ticket. The solution in Ubuntu 22.04 and any system with old curl is to manually compile and install the latest one, as shown for example here.

Importantly, the issue can be addressed on client side, you don't have to do anything with the server (especially that, in most cases, it's a third party server and works correctly).

TLDR:

apt remove curl
apt purge curl
apt-get update
apt-get install -y libssl-dev autoconf libtool make
cd /usr/local/src
wget 
unzip curl-7.88.1.zip
cd curl-7.88.1
./buildconf
./configure --with-ssl 
make
sudo make install
sudo cp /usr/local/bin/curl /usr/bin/curl
sudo ldconfig
curl -V

I just had the same issue, it looks like its an issue with OpenSSL on Ubuntu 22.04.

I just updated all my packages on the server and now functionality is working as expected.

sudo apt update && sudo apt upgrade -y

Upgrade your nginx 1.18.0 to the mainline version and the problem will be fixed. To do so:

1. Execute as sudo: curl | gpg --dearmor >/usr/share/keyrings/nginx-signing.gpg.
2. ADD THE LINES in /etc/apt/sources.list:

deb [signed-by=/usr/share/keyrings/nginx-signing.gpg]  jammy nginx
deb-src [signed-by=/usr/share/keyrings/nginx-signing.gpg]  jammy nginx

3. sudo apt update
4. sudo apt install nginx

Then restart the nginx server.

Try to upgrade your Nginx to 1.22 may help.

On Cent OS 9 Stream, you can install it with the following commmands

dnf module list nginx
dnf module reset nginx
dnf module install nginx:1.22

Another possible reason you may be getting this error is if a firewall is blocking your traffic from the machine to the internet.

In my case, it was an Ubuntu 22.04 LTS machine, behind an Azure Firewall. The firewall was configured to only allow certain categories, and the sites I was trying to talk to were not in the allowed category.

In your case it may be a different kind of rule blocking it however. You may wish to review the logs from your firewall to know if it is blocking it and why.
