some users are able to browse but other not after login in DSpace 7.3

[Thierry RUGWIZANGOGA]

Hello Team, 

I am running DSpace 7.3 which was working well till last 3 days ago. Below is the description of the issue:

1. On Some PC's (in work-group or joined to the Domain), users are able to access DSpace without any problem (Users with 1% frequent access to the application).

2. On some other  PC's (mostly joined on the Domain and Daily access to the application):

• Users are able to login,
• But some features seems freezing like Side bar (and some menu from the freeze sidebar are freezing but others responding),
• Login (for logging out) icon freeze,
• One can list Communities but can't access Sub-communities and items.

3. The above behaviour is observed on chrome,Mozilla and internet Explorer on the affected PC's.

Some troubleshoots: 

1. Decommissioned One of the affected PC's from the Domain to work-group but results are the same.

2. Cleared the Cache/Cookies of the web browser and results are the same.

3. Installed new Web browser app and results are the same.

4. Checking DevTools console/Network on chrome and i don't see any helping info as well as in the dspace logs

5. From the DevTools on Mozilla it was reporting Cookies misusing the recommended "SameSite" attribute :

Addition to the above, 

We are runing Angular
