[HamWAN PSDR] Any one having Haystack connection issues?

Hello- My HamWAN connection to Haystack has been working nicely since we set up my dish in the summer of 2019 - the last time I connected was 2 weeks ago. Tonight when I tried to log into the ACS net via Winlink, I could not connect. I tried it on two computers that I had previously connected with it, and have not messed with the software or network settings -(unless a Win 10 update messed with the networking somehow.) Has there been any issues with Haystack for any of you? I have seen no mention of it in this group or the ACS list, so I doubt it has gone down - but I have to ask before delving further. If the siteis up and running - I would appreciate any suggestions on where to start looking for Gremlins. VY 73, -John, K7HV
