too connection lost error

[sanatisharif]

we have internet connection lost error every 2s.

Our forum traffic:(screen shot)

How to fix it?

[julian]

Hi there,

Can you please provide the following information to help us debug?

1. Server-side or client-side logs
2. Server or client operating system (if applicable)
3. NodeBB version and hash
   • To get the hash, run git rev-parse HEAD from the root of your NodeBB folder
4. If applicable, theme versions
   • npm ls nodebb-theme-persona

Thanks!

1. I don't have any error in client-side or server-side, but all of users send message to us that they have "connection lost error too much"

2. our server is debian server 8, nodebb config is:

[sanatisharif]

only mobile users have such problem.

[julian]

Hm, that's interesting...

While your forum is running, can you run ./nodebb log and keep it running for awhile? It looks like NodeBB is crashing, and you are getting that MongoError whenever it happens.

Please confirm that this is always the same error you see.

[sanatisharif]

[julian]

... why are you activating new plugins?

[sanatisharif]

@julian said in too connection lost error:

... why are you activating new plugins?

I disabled it again, we needed to nodebb-ignore-users plugin.

[PitaJ]

I assume that the reason he asked is because you were already having issues, so why introduce even more variables into the mix? Fix one issue before moving on to the next.

[sanatisharif]

@pitaj @julian

at the time, I unistalled it immediately and now I am waiting for you to say what to do.
Thanks a lot

[julian]

@sanatisharif it doesn't matter, you will want to set up a duplicate instance for these sorts of things before pushing to live.

You can set one up now for debug.

[sanatisharif]

I change this line in config.json fixes my problem

"port": [4567,4568,4569]

to

"port": "4567"

why we can't use nodebb in cluster mod ?

[julian]

There is no problem with using nodebb in a cluster setup, so this config change is likely unrelated
