Aleksei

Hello
After the recent update, sometimes is happes that content is not visible and it is accompanied with error in console. All such probles are susually solved on page reload.

Stats in ACP

The statistics in ACP sometimes is not visible.

Any Forum page

Forum page doesn't show content. The preloader is spinning forever and the blue loading bar never reaches the end.

Aleksei

Also, sometimes when I reply to a thread, the editor window is not visible. Only the icon appears, but not thе window:

In this case I reload page with cache clearing (Shift + F5) to solve the issue.

Have you tried rebuilding NodeBB?

./nodebb stop
./nodebb build
./nodebb start

Aleksei

@PitaJ I didn't think about it. But performed this. We'll see how it goes. Will let you know.

Aleksei

Yes, rebuilding NodeBB helped. Thank you. The problem didn't appear since then.

Aleksei

No, sorry. The problems are still there. It happens occasionally and I cannot predict when it happens.

Aleksei

Updated to version 1.19.3, but the proble is still there. The same error.

PitaJ

Does it happen in every browser? Have you been installing plugins? Have you tried clearing your cache? Have you tried rebuilding again?

Andrey

@PitaJ Same problem. Browser - chrome. Nodebb is pure, out of the box. I'll test more. I will try firefox

Aleksei

@PitaJ I used Edge browser. I'm using a set of plugin. But last time I installed it a long time ago for an older version of Nodebb. The problem appeared after the upgrade.

Have you tried clearing your cache?

Yes

Have you tried rebuilding again?

1.19.2 — yes
1.19.3 — not yet

Another update on the topic:

Moved the entire forum to a new server.
The list of activated plugins:

nodebb-plugin-composer-default
nodebb-plugin-dbsearch
nodebb-plugin-emailer-sendgrid
nodebb-plugin-emoji
nodebb-plugin-emoji-android
nodebb-plugin-markdown
nodebb-plugin-mentions
nodebb-rewards-essentials
nodebb-theme-persona
nodebb-widget-essentials

The problem remains

PitaJ

Do you encounter any errors when building? What is your reverse proxy config?

Aleksei

Yes, I've got a few warnings:

What is your reverse proxy config?

Please, tell me how I can check it?

PitaJ

@Aleksei have you set up NodeBB to be accessed publicly with nginx or anything? That's your reverse proxy. If you're just using it locally you won't have one.

Aleksei

@PitaJ ah, got it. Yes I did it: Here it is: https://forum.c4d.space/
But I cannot guarantee that you will see the problem immediately, because I still couldn't figure out the steps to reproduce the issue.

PitaJ

I wasn't asking for your site link, though that could be helpful.

I was saying that nginx is your reverse proxy, so you should provide your nginx config.

Also try restarting nginx.

Aleksei

Below is my nginx config:
After making any changes to nginx settings I do in console 2 commands:
nginx -t
systemctl restart nginx

map $sent_http_content_type $expires {
    default                    off;

Visiting your forum now, it appears to be working fine. Are there still issues on your end?

Are you having issues on https://forum.c4d.space/ or only https://www.forum.c4d.space/ ? NodeBB only knows really works when served at a single address. What is the URL in config.json? I suggest redirecting www. to the main URL.

I'll be monitoring the status. I can't reproduce the issue. It happens occasionally.
I always access it via https://forum.c4d.space/ and this is the URL in config.json
