[fcgid:warn] [pid 30985] (104)Connection reset by peer: [client 186.136.117.5:52508] mod_fcgid: error reading data from FastCGI server
[Sun Apr 12 02:15:20.294894 2020] [core:error] [pid 30985] [client 186.136.117.5:52508] End of script output before headers: index.php
This is the error message which we are recieving in our VPS error log for each domain.
We have tried by changing fcgi to cgi and also the solution mentioned by Virtualmin support:
You may want to try a different PHP Execution Mode, it’s possible that will help, or at least produce a more informative error message. You can change that in System Settings → Website Options → PHP Execution Mode.
Nothing helps me out of this. Please have a check and let me know.
