Could not connect to your MCP server

@zonzonzon are you able to try just the below instead of adding /mcp route ? This is more generic and I hope it works across all routes.

    # compression chunking logic will interfere with SSE packet flushing
    gzip_disable "text/event-stream";

    # what responses are proxied
    gzip_proxied no-cache no-store private expired auth;

@girish I added your code snippet above, and it doesn't work. But when I add a block like mine, it works.

location /mcp {
    gzip off;
    proxy_buffering off;
    proxy_cache off;
    
    proxy_http_version 1.1;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $remote_addr;
    proxy_set_header X-Forwarded-Host $host;
    
    proxy_pass http://172.18.20.102:5678;
}

I also tested both solutions, and only yours worked properly.
Thank you for the help @zonzonzon

The correct fix needs to come from n8n - https://github.com/n8n-io/n8n/issues/14546#issuecomment-2858048370 . I guess if they don't fix it upstream , the package can bundle it's own nginx as a workaround .

@girish It seems that every time the app restarts, the nginx configuration resets to default, right? Is there any way to keep it fixed so it doesn’t change when the app restarts? Thank you.

@zonzonzon it will be fixed in Cloudron 9 . The intermediate release (8.3.2) didn't have this fix and thus you hit the issue .

@girish Any ETA for Cloudron 9?

[edwardsalfred]

Any updates on the Cloudron 9 update?

[jkammerer]

is this still an issue in the current versions of cloudron/n8n?
if i want to apply the suggested fix - on which level ist this done? root access to server?

Hello @jkammerer
It should be working.
