[Solved]Looks like your connection to NodeBB was lost, please wait while we try to reconnect.

Konrad Janczarek

I have standard error "Looks like your connection to NodeBB was lost, please wait while we try to reconnect.", I've read couple of similar topics on forum but whiteout results.

NodeBB is hosted on the same physical server as nginx server.

Here is my dump.

@Konrad-Janczarek said in Looks like your connection to NodeBB was lost, please wait while we try to reconnect.:
cat config.json

{
"url": "http://domain",
"secret": "secret***************************",
"database": "mongo",
"mongo": {
"host": "localhost",
"port": "27017",
"username": "name",
"password": "passwd",
"database": "db",
"uri": ""
},
"port": "4567"
}

Changed to
cat config.json
{
"url": "http://domain:4567",
"secret": "secret***************************",
"database": "mongo",
"mongo": {
"host": "localhost",
"port": "27017",
"username": "name",
"password": "passwd",
"database": "db",
"uri": ""
},
"port": "4567"
}

and it's works.

Sorry for same additional topic.

That's not actually what's wrong, your config.json was correct. The problem is your nginx config is wrong. Follow the docs here.
