Can no longer access Nextcloud via great internet?

I’m looking for some help here… I have what seems to be a att connection problem but I cannot nail it down. Nextcloud works fine for a year but since last Friday we are unable to access it from the greater internet (Intranet works fine).
I’ve called ATT but they are useless… the address is https://cloud.gregorigroup.com

other http services on the same network are working fine… I just can’t get to nextcloud. Any network people who can help?

If I open the URL, I can see the login screen.

same here.

Looks like every thing works fine from here.

Tried classic browser temp memory & cookies flush?

Edit: lol didn’t see the tread is almost 8 month old… :slight_smile:
