Is it a subdomain method setup?
After setup the network with the subdomain method, you will need to login to the web admin panel to add the subdomain to VHost Template > docker > [Your Virtual Host Name]> Domain Name
I just tested it and it works.
I understand that but what will happen when OLS will update, this file will update too and made changes would be lost?
It shouldn't, you can give it a try
For those settings,
Please check Request/Response from the Web Admin > Server Configuration > Tuning
Please check Index Files section from...
Docker Desktop on windows should work, but I am not sure about WSL,
Saw a similar issue, hope it helps.
