Any special considerations for Blazor Server apps?

Posted on January 22, 2025

A while ago I tried deploying a Blazor Server app on DigitalOcean, and it didn’t work. It deployed okay, but had a lot of console errors related to sockets/SignalR. Has anything changed here recently? Is there some kind of config tweak that would solve this? Would love not to be locked into Azure for Blazor Server apps.

Heya, @adamfoneil

If you’re using a reverse proxy like Nginx or Apache, additional configuration is necessary to support WebSocket connections. For Nginx, you need to set specific headers and upgrade connection settings to handle WebSocket traffic properly. Misconfigurations here can lead to SignalR connection issues.

Are you using the App Platform or Blazor is configured on a droplet?
