OpenSSL Error messages: error:0A000126:SSL routines::unexpected eof while reading

Question

Screenshot is here

I have built a website in PHP using the YII2 framework. When I use file_get_contents($requestUrl, false, stream_context_create($arrContextOptions)) then i am getting error saying error:0A000126:SSL routines::unexpected eof while reading I have also tried to enable the legacy provider by editing the openssl.cnf file, but got no success. Reference: https://gist.github.com/rdh27785/97210d439a280063bd768006450c435d

Any help would be appriciated.

Server: Nginx (nginx/1.18.0) OS: Ubuntu 22.04 LTS PHP: 7.4.29 Openssl: 1.1.1d

Answer 1

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 https://curl.haxx.se/download/curl-7.88.1.zip
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
