For someone meet same problem, after serves hours debug I found that Nextcloud docker container cannot resolve ucs host so I check DNS record and found that IP of DNS server already decreased 1 from 10.0.1.47 to 10.0.1.46
at reverse zone
image
and forward lookup zone
image
So just modify DNS record to UCS IP (in my case is 10.0.1.47) it will work!
