V.0.56.0 breaking sync with self hosted server (desktop and android)

WHAT IS THE BUG Self-hosted sync completely breaks after updating the Windows desktop client to v0.56.0. The client fails to connect to the self-hosted node and throws an EOF handshake error (gRPC connection drop). The issue is entirely client-side, as downgrading back to v0.55.x instantly resolves the issue with zero changes to the server infrastructure.

HOW TO REPRODUCE IT

  1. Run a self-hosted Anytype network via Docker (updated to the latest node versions).

  2. Route the traffic through a reverse proxy (in my case, Nginx Proxy Manager on a VPS).

  3. Update the Windows desktop client to v0.56.0.

  4. Attempt to log in or sync using the self-hosted network .yml config file.

  5. See the sync fail completely due to an EOF handshake error.

THE EXPECTED BEHAVIOR The client should successfully connect, authenticate, and sync with the self-hosted node through the reverse proxy, exactly as it seamlessly does in version 0.55.x.

ADDITIONAL CONTEXT

  • The definitive proof: Completely uninstalling v0.56.0, clearing the %APPDATA%\Anytype cache, and installing v0.55.x restores full functionality immediately using the exact same .yml file.

  • My setup consists of Docker nodes running on Unraid, tunneled through a Hetzner VPS running Nginx Proxy Manager.

  • The issue seems to be a regression in v0.56.0 regarding how the client handles mTLS certificates or gRPC streams when connecting through a standard reverse proxy.

  • Node logs during v0.56.0 connection attempts via local IP bypass showed absolutely zero incoming connection attempts reaching the any-sync-node-1 container, further pointing to a network routing/handshake issue introduced in the new client version.

TECHNICAL INFORMATION

  • OS: Windows 10/11

  • Client Version (Failing): v0.56.0

  • Client Version (Working): v0.55.x

  • Server Setup: Docker on Unraid + Nginx Proxy Manager

Thank you for reporting. We’ve flagged these issues and are looking into it.

We have released a new any-sync protocol, and an upgrade is necessary. We will work on improving the UI to notify users when this happens.

Hi! Can you please share what node version are you running?

docker ps -a

  • If all of them are v0.11.x or v0.12.x, they should work, we need to debug. It would be helpful if you could send a Debug - Export Report from the desktop app. You can send it to [email protected].
  • If they are older than v0.11, you need to run make update.
  • If they are v0.11, it still makes sense to try to update to the latest version and see if it help
