Debugging Server Connectivity Issues: IP Address Changes

TL;DR

• Erased and rebuilt the Metro cache to troubleshoot server connection issues.
• Discovered system IP address changed, causing server/client disconnection.
• IP change likely due to dynamic IP settings and brief network drop.
• Metro server maintained connection despite IP change; suspected cache of network addresses.

Debugging Steps

When troubleshooting why the server wasn’t receiving client requests, I initially didn’t consider rebuilding the Metro cache. Once I did, I noticed connection timeouts. Further investigation revealed that my macOS system’s IP address had changed, leading to the servers being split across different IPs.

The issue likely arose from network connectivity being temporarily lost, triggering the dynamic IP system to reset. This change meant connections were trying to link to outdated network locations. I suspect Metro’s caching mechanism retained older IP address information for some services, which explains why certain aspects functioned while others failed.

Next time, addressing dynamic network configurations upfront might save time and reduce distractions.
