Robert. Thank you for taking the time to look into my question, I was in a rush and didn't formulate my question very well, the problem is when trying to search for features using the buffer, It works great inside the county network but for the general public it doesn't. I triple check the proxy settings, I asked IT to modify the F5 firewall, I upgraded the security of the web server but can not figure it out this issue.
It also does not when performing the second query the first query works fine (in case this helps):
SQL Where with layers definition expression: Upper(PIN) = Upper('33300110900000040010000000')
SQL Where with layers definition expression: MUNICIPAL = 'BLOOMING GROVE' AND Upper(PRINT_KEY) = Upper('1-1-1')
