Hello everyone, this is my first time using Syncthing. I discovered it in 2025 because I installed a microserver at home, but I'm having trouble with the network. It returns the following message:
****
Discovery Failures
The following methods are used to discover other devices on the network and announce that this device is discoverable to others:
Local IPv4
Local IPv6
global@https://discovery-announce-v4.syncthing.net/v2/
global@https://discovery-lookup.syncthing.net/v2/
Some discovery methods could not be established to discover other devices or announce this device:
global@https://discovery-announce-v6.syncthing.net/v2/: Post "https://discovery-announce-v6.syncthing.net/v2/": dial tcp [2a01:4f8:162:11f2::2]:443: connect: network is unreachable
Failure to connect to IPv6 servers is expected if there is no IPv6 connectivity.

I don't have much experience with Linux; I'm configuring it by force, using videos and forums. However, I've only found vague answers to this problem in previous years. My router is a Tenda router, and I don't know how to use this tool to automatically sync my smartphone.
This error is expected and can be ignored if your Internet connection doesn’t support IPv6. If you’re experiencing connectivity issues, this is very unlikely to be related unless you’re connecting to an IPv6-only device. Or as the web GUI says:
