One thing to keep in mind is that while you appear to have functionality at this time, it is not recommended to use outdate versions of PHP Extensions, especially when you are on the Latest Stable Version of the 8.0.x branch
Just to try and figure out the versions we are dealing with here, what is the output that you get in the shell if you use the command 
php -i | grep -i curl Which one once of my servers outputs the following:
sysadmin@mail:~$ php -i | grep -i curl /etc/php/8.1/cli/conf.d/20-curl.ini, curl cURL support => enabled cURL Information => 7.68.0 curl.cainfo => no value => no value Just my 2 cents here.

What errors have you not been able to resolve on your own?

Are past version available for download anywhere?
I am have a plan to port an old modification, but will need an older version of it to start the process on my test server.
