I am just trying to sercure my Nextcloud and get acces from external.
I setup Nextcloud in docker with the How To Video of TechnoDadLife at the first step.
Then tried to get it worked with the second Video HowTo of TDL >
But at the end I can`t access Nextcloud. Not from external and not from internal anymore.
502 Bad Gateway
Portforwarding ist working.
I get the Letsencrypt Cirtificate in my Browser and can see my SubDomain.
Does someone have an idea how I can troubleshoot this error?
Many thanks in advanced.
Answers in german or russian would be fine too.
