[Ryaan J.]

Hi, need to set up stunnel with squid proxy in ubuntu 22. When i restart stunnel as /etc/init.d/stunnel4 restart ** encountered the following error: Job for stunnel4.service failed because the control process exited with error code.

You can solve that error by checking the Stunnel installation and stunnel.conf file for any wrong configurations:

Check /etc/stunnel/stunnel.conf file for syntax errors.

And test it using: stunnel /etc/stunnel/stunnel.conf

Ensure your configuration file has the necessary settings. Here’s a an example:

client = no

[https]

accept = 443

connect = 3128

cert = /etc/stunnel/stunnel.pem

key = /etc/stunnel/stunnel.key

Check If Stunnel Is Installed Correctly: dpkg -l | grep stunnel
