Connection issue to PCS

Good Afternoon,

I am having issues ever since I upgraded to windows 11.  I see that my PCs show connected by clicking the cog, configure computer, then clicking the cog with the green check.  I get the message "multiplicity was able to successfully connect to this computer"  however my mouse will not go into that screen...   

Sometimes when i restart all the pcs it will fix it... sometimes it wont.   I am not sure what to do ... I checked the IPs they are correct.. I never use to have these issues.  No router has been changed,  same 3 PCs since I got this over a year ago.
