PROBLEM: Pool Member Won't Work Through Big IP LTM

Sorry to keep responding to myself, but now I'm just going insane. So while I thought I was able to simulate the GET request via telnet on the F5 to the Virtual Host, I tried again today only to find out I couldn't, apparently for either member.

 

 

Then I realized I can just do a GET command (didn't realize yesterday it was case sensitive). So now if I ssh into F5 and GET, it works fine if only the good member is active in the pool, I can GET to the Virtual Host successfully. And I can also do a GET to the good server directly. But here's where it gets weird...

 

 

I can only occasionally GET from F5 to bad member through virtual host AND its server IP. In other words, it sometimes works for a little bit, but often it just simply returns:

 

 

500 Server closed connection without sending any data back

 

 

And sometimes I can GET directly to bad server IP but not do it through Virtual Server. Also I believe that even when I can't GET to the bad server ip directly, that I can do a WGET on my client to the server directly successfully.

 

 

It's getting very hard to even decide how to troubleshoot with this being so inconsistent.
