Connection problems
- Refresh and check whether the service is reachable.
- Try another network if messages or calls fail.
- Check browser permissions and private-mode restrictions.
- Do not repeatedly create accounts when a rate limit is already active.
Messages not sending
Check connectivity and session state. If the UI loads but sending fails, capture the exact browser-console error and HTTP status before changing server files.
Calls not connecting
Check microphone/camera permissions, then test two separate devices. If signalling works but media does not, investigate ICE/STUN/TURN and firewall/NAT configuration.
Files not uploading
Check size, quota and network. If an upload returns 403 or 429, record the endpoint and response before weakening security middleware such as ModSecurity.
