Please help me to solve the following problem:
I had installed WebTop5 with the “Use a virtual host for WebTop” option, access being done through https://webmail.mydomain.tld.
Due to some problems that occurred when obtaining the Let’s Encrypt SSL certificate, I de-selected the option to use via virtual host, at the same time changing the Public URL to https://mydomain.tld/webtop.
After this change, I can no longer access WebTop from the WAN except through https:/mydomainIP/webtop.
For Nexcloud I made the same change without problems.
