I'm having a strange issue with HopToDesk and would like to know if anyone else has experienced this.

Environment:

• HopToDesk version: 1.45.25
• Windows 11
• Both local and remote PCs show "Ready" (green status)
• Both devices have valid IDs
• Internet connection is working normally on both sides

Error message:

"Both connections failed. Direct: direct connection failed, Relay: Failed to connect via relay server: all candidates exhausted (last error: all 5 candidate(s) failed to allocate)"

What I've already checked:

• Both PCs are online and show Ready
• Correct device ID entered
• DNS resolution works (api.hoptodesk.com resolves correctly)
• HopToDesk logs show: "INFO [src\server.rs:648] config2 synced"
• Tried using a mobile hotspot instead of the normal network
• Disabled IPv6
• Flushed DNS cache
• No obvious firewall issues

Important:

• RustDesk works perfectly between the same two PCs.
• Only HopToDesk fails.

Because both devices are connected to the HopToDesk servers and show Ready, I'm wondering if this could be a relay server issue, a bug in version 1.45.25, or something related to TURN allocation.

Has anyone seen this exact error recently?

Any suggestions would be appreciated.
