Do you want to request a feature or report a bug? bug What is the current behavior?

Error when trying to connect (cURL error 35: OpenSSL/3.1.4: error:0A000438:SSL routines::tlsv1 alert internal error (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for https://xx.com/healthcheck)

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem. Hello, I want to use OnlyOffice for NextCloud, I deployed it in my home network with a dynamic public IP but not open port 80 443, so I used port 7980 instead of 80 and 9780 instead of 443, I used Docker for the installation, the installation command is as follows:

sudo docker run -i -t -d -p 9003:80 --restart=always \
    -v /app/onlyoffice/DocumentServer/logs:/var/log/onlyoffice  \
    -v /app/onlyoffice/DocumentServer/data:/var/www/onlyoffice/Data  \
    -v /app/onlyoffice/DocumentServer/lib:/var/lib/onlyoffice \
    -v /app/onlyoffice/DocumentServer/setting:/etc/onlyoffice \
    -v /app/onlyoffice/DocumentServer/db:/var/lib/postgresql -e JWT_SECRET=WIy4qCH1fE3k5f3J onlyoffice/documentserver

As shown in the command, I mapped port 80 443 within Docker to port 9003 9004 of the server respectively, I deployed OpenResty on the same server, and used a reverse proxy to proxy port 9003 to ports 7980 and 9780, and because NextCloud requires HTTPS, I also 301ed 7980 to 9780 and resolved to xx.com, then when I visited https://xx.com:9780/ , it should go to https://xx.com:9780/welcome/ , but it actually went to https://xx.com/welcome/, manually visit https://xx.com:9780/welcome/ can be opened normally. Fill https://xx.com:9780/ into ONLYOFFICE Docs address, and check Disable certificate verification (insecure), it will prompt:

Put https://192.168.4.3:9004/ in to the ONLYOFFICE Docs address and check Disable certificate verification (insecure), it can be used normally, but only for intranet environment. What is the expected behavior? can be used Did this work in previous versions of DocumentServer? unknown DocumentServer Docker tag: 7.5.1 Host Operating System: debian-12.2 x86_64
