URGENT: `What is My ISP?` tool's `ip address lookup` breaking, seeing constant API errors!

just lost my mind trying to fix our 'What is My ISP?' tool, it's driving me absolutely insane. the core ip address lookup functionality is randomly breaking, users are getting wrong ISP info or just empty results. it's not consistent, which makes it even harder to debug.

i'm seeing these weird API timeout or malformed response errors in the console/logs. i'll put a fake example log here to show what i mean:

[2023-10-26 14:35:11] ERROR: GEO_IP_SERVICE: Request failed for 192.168.1.100 - Timeout after 5000ms.
Response: (empty or malformed JSON)
[2023-10-26 14:35:12] WARNING: ISP_DETECTION: Could not retrieve ISP data for user IP. Falling back to default.
[2023-10-26 14:35:13] ERROR: GEO_IP_SERVICE: recieved unexpected status code 403 for 203.0.113.45.

i've tried checking API rate limits, switched to a different IP geo-location provider, even restarted the whole server, but nothing seems to stick. feels like hitting a wall. really desperate for any ideas or anyone who's faced similar issues with ip address lookup services. help a brother out please...
