Any crawl issues with TLS 1.3?

[TimDickey]

Not a techie here...maybe this is to be expected, but ever since one of my client sites has switched to TLS 1.3, I've had a couple of crawl issues and other hiccups.

First, I noticed that I can't use HTTPSTATUS.io any more...it renders an error message for URLs on the site in question. I wrote to their support desk and they said they haven't updated to 1.3 yet. Bummer, because I loved httpstatus.io's functionality, esp. getting bulk reports.

Also, my Moz campaign crawls were failing. We are setting up a robots.txt directive to allow rogerbot (and the other bot), and will see if that works. These fails are consistent with the date we switched to 1.3, and some testing confirmed it.

Anyone else seeing these types of issues, and can suggest any workarounds, solves, hacks to make my life easier? (including an alternative to httpstatus.io...I have and use screaming frog...not as slick, I'm afraid!)

Do you think there was a configuration error with the client's TLS 1.3 upgrade, or maybe they're using a problematic/older version of 1.3??

Thanks -
