Not sure if anyone is still having problems but I have the same issue with a brand new Samsung S21 phone it would say Log in timed out. Yet it worked on my old phone and tablet with no issues. So this is what fixed my issue after working with tech support. I factory defaulted the NVR and was able to login. But when I loaded my config backup it started to get the login timed out again. Factory default of the NVR again was able to login but this time I tried added the cameras manually, after that Everything worked fine no issues it was able to login. Not sure what the issue was with it being a new Samsung S21 but this fix the issue of log in for me, hope that helps.
