Constantly being told “you can’t access the site from that IP address”…from everything except my cell phone. Even after setting third party auth I get the same message. Anyone else experience this or more importantly know how to fix the issue. This occurs from both work and home computers…
Yeah, we’ve had a lot of reports of this issue.
I sometimes get it from work, but not home.
We’ve yet to track down what on earth is causing it though 
Oh I may have a lead on this. I got it yesterday when trying to log in from my laptop.
Connecting with HTTPS instead of HTTP seemed to have resolved the issue and allowed me to log in. I never have a problem logging in with Google Chrome, but on my laptop I run Firefox. I was reading here that for navigations which don’t specify a protocol, HTTPS is the default in Chrome. Maybe that’s not the case for Firefox.
Login works for me on https://discourse.techart.online
But not on https://tech-artists.org
@Theodox any idea why besides https certs being super weird and spooky?
@BenWall’s comment got me thinking so I did a few tests. It doesn’t actually seem to be https.
If I go to tech-artists.org and attempt to login, pressing the “Log In” button will take me to discourse.techart.online, and I will not appear to be logged in. If I then navigate back to tech-artists.org, I will be logged in.
If I try to log in again from discourse.techart.online instead of navigating back to tech-artists.org, that is when I will get the “can’t login from that IP address” error.
I’m seeing this behavior on both Chrome and Firefox. I can’t seem to log in at all on Edge. There was a strange scenario where I lost the ability to log in on either site in Chrome and had to email myself a login link, which successfully logged me into discourse.techart.online, logging out again allowed me to repeat the earlier scenario. Seems strange to me, but this happened in 1 out of 5 tests that I did so it might have been a fluke.
I just reproed JoDaRobers method and I managed to log in as he specified by navigating back to tech-artist.org. This occurs on Chrome and Edge for me.
I think I’ve found the root cause:

Can’t access that link, but I can confirm that I managed to login from a few different PCs with two-point auth on the discourse.techart.online web page.
