"Connection Lost" warning


I have the warning “Connection Lost” when editing a workflow. Can’t find the save button anymore. However, is I click on “workflows” to go home I have the popup asking me to save and it is working properly.

I recently upgraded from beta to 1.3.1, is it a known bug ?

Thanks for your answer

Are there any workaround ? Currently, to save my workflow I have to go back to the workflow list. Are you aware of any other trick to be able to save current workflow ?

HI @Valerian_Lebert :wave: I’m unfortunately not aware of any workaround on this one at the moment :see_no_evil: You’ll be sure to know when there’s an update around this, though!

Hi @EmeraldHerald

I realized that this issue is more criticat than I thought : I can’t create a new webhook trigger for example.

When clicking “listen for events” I have the error connection lost to the server. Impossible to initialize the webhook trigger

I could fix my issue thanks to this post

I had change my nginx conf for websocket support

    location / {
        proxy_pass http://localhost:5678;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade; # websocket support
        proxy_set_header Connection "Upgrade";  # websocket support
        proxy_set_header Host $host;
        chunked_transfer_encoding off;
        proxy_buffering off;
        proxy_cache off;

HI @Valerian_Lebert - so sorry that you were having such a critical issue, but thank you so much for posting your solution!
