I just started receiving this error today when trying through ArcMap 10.5.1 to add data or a base map from ArcGIS Online. ESRI support recommended the patch TLS which deals with the change that will occur in April 2019 for HTTPS, however, I am the only one receiving this errors as of now in my organization and no one else has implemented this patch. Could this be an IIS issue as I am the only one who uses web Application Builder and publishing to ArcGIS Server?
Solved! Go to Solution.
George,
Take a look at this article:
Esri Support Esri Software Products Affected by TLS 1.2 Implementation
I received an email about this since I'm an admin in my AGOL group (at least I think that's why, or an admin in my org).
For 10.5, you will need to go through these steps to install the patch

But this TLS patch takes affect for April 2019 security change
Yeah, true. Good point. Maybe it would be a good idea to install it anyway to see if you get past those errors?
Ok the patch did resolve this issue, I guess April 16th came early.
Ha, who knew! I am glad it worked.
Hi George,
Glad that the patch got you up and running, but like you mentioned in the previous messages, you shouldn't be seeing that error connecting to ArcGIS Online until after the update in April (if the patch isn't installed).
If you go to ArcGIS Administrator > Advanced... > Manage Portal Connections...
Are there any other connections listed there besides arcgis.com? I ask because if you are connected to another portal that enforces TLS 1.2 only, you would get that error.
Another thing you might want to check is your internet settings. If you're not allowed to use TLS 1.0 or 1.1 at the Operating System level, that might be another cause for the error before you installed the patch. You can check that by searching "Internet Options" in Windows > Advanced > Scroll down to the Security section and see what "Use TLS 1.x" options are checked on/off.

I do have use TSL 1X checked on, but in arcgis administrtor i did see this.
That'll do it! That's the URL used to validate that the patch is working successfully. That URL enforces TLS 1.2 only and would cause an error if you don't have the patch installed. See more here: How To: Validate TLS 1.2 connections for ArcGIS Desktop
Make sure you switch back to using the arcgis.com portal (select http://www.arcgis.com/ in the list and click Connect) so that you can sign in to your organization and access your content again. And now that you've got the patch installed you should be good to go come April 16!
Hope this helps, let me know if you have any other questions.
