Might be related to #8815.

Try running npm install and then ./nodebb upgrade

[mysterydata]

Try running npm install and then ./nodebb upgrade

tried same issue

[mysterydata]

any idea as this forum is running in production and down for 5+ hrs now, can we resolve it quickly or wait for the next release ?

[barisusakli]

What are the versions of these dependencies on your install?

"@nodebb/mubsub": "1.7.0",
"@nodebb/socket.io-adapter-mongo": "3.1.0",

[mysterydata]

$ npm list | grep mubsub
├─┬ @nodebb/[email protected]
│ ├── @nodebb/[email protected] deduped

$ npm list | grep socket.io-adapter-mongo
├─┬ @nodebb/[email protected]

[barisusakli]

Are you on mongodb 4.4.x as well?

[mysterydata]

Are you on mongodb 4.4.x as well?

yes

$ mongo
MongoDB shell version v4.4.1

[sandratatarevicova]

@mysterydata do you have multiple ports in config.json? If yes, try to set only one port instead of the array of ports.

[barisusakli]

Yeah that would fix the issue until I can publish the fix in @nodebb/mubsub.

[barisusakli]

Please install
"@nodebb/mubsub": "1.7.1",
"@nodebb/socket.io-adapter-mongo": "3.1.1",

and try again, let me know if you are still having issues.

[mysterydata]

thanks solved.

[barisusakli]

Gonna reopen this for visibility until we release 1.15.1
