I did a clean install of Iredmail 1.6.2 on the ROKYLINUX distro, but when I try to access roundcubemail https://ip_server/mail I get error internal :Oops... something went wrong!
An internal error has occurred. Your request cannot be processed at this time

However, when I access https://ip-server/iredadmin, it accesses me without problems, reviewing the nginx logs I get the following output:

PS: I've been using and installing iRedmail for more than 5 years and I've installed all of them until now that I want to migrate my current rokylinux 8 mail server to rokylinux 9
