Issue with nextcloud in two linux pcs log in/out

with my work I have a nextcloud account associated. and installed the nextcloud sync client the exact version of it is: 3.11.1tux1 (I am using tuxedOS 2 in the two pcs). my issue is that the account is always log in out… it keeps all the info about the acount, but sometimes I look at it and it says ‘log in’ which is quite annoying specially as one of the pcs is fixed at my work and I find myself not being able to acces to some documents. is there anything in particular that I should configure or do? (I have kwalletManager which saves the passwords activated).
sorry i can not give any more info but I am a little bit lost about the issue itself…
thanks in advance
