OMV 6 and no GUI after few days after install

hello guys, first of all sorry for my poor English. I will try to explain what happening.

I saw OMV 6 and i like it too much and reinstall my computer with OMV6, but after few days i cant open the site. I change port from 80 > 8085 because Nginx want 80 port and i got many problems before with him. To be honest i don't want to start command "first-aid" , because all things working perfectly and its will be pain in ass if i reinstall it again...

Someone can help me? I can give anydesk to log in my computer and try to help me.

edit: stop nginx and change port to 80 and and give me white blank window. anyway not working

Thank you in advance.

Regards Cage

if i removed apache, my site will go down...

okay guys, i removed apache2 and all thigs with apache2,restart machine, change port from omv-firstaid to 80 and still cant open GUI... i give up...
