SharePoint 2019 Crawler not working on one site.

I have a 2019 on prem SharePoint server running. I've not had an issue with crawling until recently.

For some reason all crawling quit working after a reboot of the server so I just deleted the Search Service app and created a new one. No issues doing that.

After assigning permissions and making sure the service was running. I checked the Crawl log. We have 3 SharePoint Sites that are listed in the Content Sources for Crawling. http://servername:2121 - site2 http://servername:17195 - mysites http://servername:39064 - site1

Crawling works perfect for site2 and mysites. The issue is with site1 I get the following warning for it

Item not crawled due to one of the following reasons: Preventive crawl rule; Specified content source hops/depth exceeded; URL has query string parameter; Required protocol handler not found; Preventive robots directive. ( This item was deleted because it was excluded by a crawl rule. )

I've searched and tried just about everything I can find. Site1 and Site2 are almost identical so I don't understand why it works for one but not the other. I can browse to either just fine. Any suggestions on what else to look at?

Things I've Tried: 
I made sure there are no crawl rules
I created a new crawl rule to include the affected URL
No Robots.txt file at all
Created new content source with just site1 in it to test
