I run NodeBB on a CentOS server, which is a Hyper-V virtual machine. And I pass requests via a IIS server with ARR. I'm sure it works fine with websocket. It works OK when I have few members. But, when I put it online, I get something strange: members on my site sometimes logged in as others. Let me describe it more clearly : my username is oott123 as you can see, but after I visit some pages, or logged in after some while, I can see someone else 's avatar displayed on the top right corner. If I post a topic , the author will be he, not me. All of my operations seems operated by others. My code is here: https://gist.github.com/oott123/66a507a2cadbb26415aa I want to get the CIVITAS-Authentication cookie which has been setted by other applications without error; then send it to my API server to get email identified by CIVITAS-Authentication; then logged the user in. I think the problem is caused by the code around line 86 or 143. I even thinked about it's caused by async or node.js event loop, orz. There's some Chinese character in the comments, but you can ignore it. Thanks a lot for help me , and sorry for my poor English again. -- @a_5mith So do you still remember me at Topic 2593 ? I just really love NodeBB, so I hope there's some way to help me troubleshot it .

@baris ok i upgrade redis-server to 2.8 but i forget to backup the database. So the new version of redis delete the forum database. I restore an old one with one or two missing posts. Everything works great now. Thanks

@anooxy said: @psychobunny I got no users now, did they rename the dump.rdb? Possibly, yes. The new redis config might have changed the database file from "dump.rdb" to "redis.rdb". Go into /var/lib/redis and save a backup copy of dump.rdb, it's probably the bigger one (since the other one is empty). Then turn off redis: sudo stop redis-server Then check /etc/redis/redis.conf for the dbfilename option, and check that it is set to dump.rdb. Start redis: sudo start redis-server
