Steps to Reproduce

Here's the code I'm using:

# main.py
import rpa as r

if __name__ == '__main__':
    r.init(visual_automation=False, turbo_mode=False)

$ python3 main.py 
[RPA][ERROR] - following happens when starting TagUI...

The following command is executed to start TagUI -
"/home/austinm/.tagui/src/tagui" rpa_python chrome

It leads to following output when starting TagUI -
Auto configuration failed

[RPA][ERROR] - unknown error encountered

Workaround

The workaround is to edit the /etc/ssl/openssl.cnf file and comment out the following lines:

providers = provider_sect
ssl_conf = ssl_sect

Hi @austin-millan thanks for raising this issue, providing detailed context, and sharing your solution!

Python rpa package uses TagUI RPA engine, which uses the PhantomJS headless browser as its JavaScript engine. PhantomJS has a dependency on OpenSSL, which might be the reason for this apparent conflict in your environment. For Mac, there is auto-patching already implemented to fix an issue with OpenSSL/LibreSSL. For Linux, I haven't gotten users feedback that it is affecting Linux users broadly, and thus there isn't any automated-patching during init().

Could you try downloading below PhantomJS for Linux, and replace your copy at ~/.tagui/src/phantomjs, to see if that works without your workaround above? If it does, I'll have to watch out for more users feedback, to see if that justify auto-patching with that PhantomJS Linux binary. If it doesn't, I still want to store this workaround solution somewhere so that other users can add on to this issue. And hopefully I can build in a fix that doesn't compromise other existing Linux users.
