Nginx & Varnish & Apache SSL no work

Hello, I have this problem, if I use only Apache SSL it works without problems, but if I change it to Nginx & Varnish & Apache it stops working and it gives error 500, and it repairs the permissions, possibly it is a problem of ports?
HTTP: Nginx (80) -> Varnish (82) -> Apache (8181)
HTTPS: Nginx (443) -> Varnish (82) -> Apache (8181)

Same here, I got a notification message to install the php function thingy, and it basically crashed the server, when the server got back up online, i choose the fastest one - the radio button at the bottom -- now i have a 502 bad gateway - i cant login to CWP, or via FTP...

Try deleting and reinstalling the SSL certs after you have run domain conf. Worked for me.
