OpenSSL (CURL Error: 56 - OpenSSL SSL_read: error:0A000126:SSL routines::unexpected eof while reading, errno 0) Issue on non-cPanel WHMCS

Hey all, looking for some guidance on this OpenSSL issue 

CURL Error: 56 - OpenSSL SSL_read: error:0A000126:SSL routines::unexpected eof while reading, errno 0

 

when connecting to the eNom API for a WHMCS installation that exists independently of cPanel (this is not helpful Troubleshooting CURL Error: 56 - OpenSSL SSL_read: Success error | Troubleshooting | Guides & Tutorials (whmcs.com)).

The only community articles I seem to find relate to WHMCS environments running on a cPanel server managed by EasyApache, this isn't the case when running on it's own VM.

Environment Details:

PHP Version 8.1.2-1ubuntu2.8

cURL support: enabled

cURL Information: 7.81.0

Apache/2.4.52

Any love here?

I'm having this problem too. The problem appears to be that that curl on Ubuntu 22.04 (and perhaps others) used OpenSSL v3 , and that is stricter with connections that v1. That causes connections to the eNom API to fail, I assume because eNom uses older SSL algorithms. So strictly speaking the problem is with eNom, and I'll open a ticket with them about this, but I'm a sub-reseller, they're not going to take any notice of me for this.

I thought upgrading my PHP version might help, but unfortunately not. Still looking for workarounds.
