Hi All,
My app lication team is getting error 502 Bad Gateway when they try to access below URL:
For eg: www.xyz.com/lib/dict.en-US.json
Below is the traffic flow.
Public --->>> DNS --> CDN ---> F5 --|||-> LB (10.x.x.x) ---> Apache servers (10.x.x.x1 & x2)
I have few policies on VIP which says if the request comes with above URI redirect it to a new pool.
I told app team 502 error is related to server only. Can someone hele here what things I can check on F5 to tshoot this issue.
Thanks,
Solved! Go to Solution.

Hi @ashish_solanki,
pity you have to prove your innocence here. My standard answer to such accusations usually is: "The BIG-IP does not send a HTML page unless it is configured to do so."
Before you make such a bold statement with confidence, you should check that your configuration on the BIG-IP is correct. You can do the following to further analyze the issue and to verify your config is working as intended:
Good luck,
Daniel
