I think codeforces must change some config in it's server. I tried oj login https://codeforces.com/contest/1763/problem/A just now( 2022-12-31 12:59:30 )with the cookies.jar created in above(12-25), it works properly. It is very weird

I think if the server change again, this issue should be still can reproduce, but now the oj working properly.
