Mac to Mac connection problems.
Greetings All,
When I attempt to connect my home Mac to my work Mac, my work Mac will initially indicate that it is online (usually for 1 or 2 minutes), when I attempt to connect to my work Mac it will immediately fail and then indicate that it is Offline. It will stay offline for several hours. This is recurring problem with a failure rate almost 100%. For the first few months that we were remote working, I had no problems connecting. This began around mid-September. My IT director and I have gone through the most likely fixes such as firewalls and antivirus software without success. The office Mac is running Yosemite, the home Mac is running Big Sur although this problem began when both were running Yosemite.
Any ideas would be appreciated.
