UCP users gets auto logged out on PC

Good day

We are using a Songoma appliance with FreePBX as the VoIP Server, all the servers is up to date,

We use the UCP for the different users to download there calls, 99.9% of the users works perfectly except for 3,

They go to our address xxx.xxx.xxx.xxx/ucp and log in with there credentials as soos as they log in it logs them out again and the address just changes to xxx.xxx.xxx.xxx/ucp?logout=0

all their cache has been cleaned and it is happening on all there browsers, on another PC they can log in and it works fine,

can someone help to get this solved, thinking it could be PC issue?

Regards
