GUI cannot connect to peers - Discovery servers return HTTP 502

[mithat-maker]

Describe the bug
After installing Eigenwallet via the official Flatpak guide on Linux Mint, the GUI never connects to peers and remains at "Connected to 0 peers".

Tor starts successfully and both wallets load correctly, but no peer connection is established.

The libp2p logs repeatedly show:

server rejected handshake; status code = 502

I also tested the discovery servers manually:

curl -I https://discovery.eigenwallet.org
HTTP/2 502

curl -I https://discovery2.eigenwallet.org
HTTP/2 502

The problem persists after:

• restarting the application
• disabling Mullvad VPN
• reinstalling using the official Flatpak installation guide

The discovery endpoints themselves currently return HTTP 502 from Cloudflare when tested manually with curl.

Platform (please complete the following information):

• CLI or ASB GUI (Flatpak)

this seems to be an issue with the rendezvous servers itself. it has nothing to do with the gui not being able to connect to peers. its just that the default rendezvous servers are currently not working.

any clients having issues of no discovery

go to settings
find rendezvous points, click little pencil icon
scroll down, add:
/onion3/v3qmlnnutkrmc6kizg2v3q22tox3oh4lkmehcnqubk3yj4p6tunmtoqd:8888/p2p/12D3KooWDwtPvaPeiuLi7TwP7wMaZiwY3t3Sm6h7c23vxswTWAg5

click little + plus icon. close. restart GUI.

this will add a working rendezvous node to your GUI

fixes:
(PR #1152)
also to avoid such problems like all rendezvous not working properly, we should save to database known peers (with some limitations and expiry of course), not just wormholes (that are broken in the current implementation, because they are inactive after a while and then block the dial completely, #1151). i was already working into this direction, however not even the 3 weeks old PRs are merged yet. i will continue on this later.

Thanks! That solved the issue.

After adding the rendezvous point and restarting the GUI, peers started appearing again and the wallet is now able to discover peers.

The default rendezvous servers were indeed the problem in my case.

Thanks for the workaround!
