@BDHarrington7 Can't believe it! Now I believe in miracles
Here's what I did:

1) git fetch

2) git describe --tags
v0.6.0

3) ./nodebb upgrade
Successful with some database schema update

4) ./nodebb start
Works like a charm

5) git checkout v0.6.1
6) ./nodebb upgrade
Successful with a bunch of database schema updates

7) ./nodebb start
working perfectly

8) git describe --tags
v0.6.1

9) git checkout v0.7.0
Previous HEAD position was 4686ae9... 0.6.1
HEAD is now at 43b90c5... fixed #3218

10) ./nodebb upgrade
NodeBB v0.7.0 Copyright (C) 2013-2014 NodeBB Inc.
bunch of info messages and database schema update

11) ./nodebb start
Gosh! Finally!!!

And yes, now I believe it's perfectly possible to upgrade 0.6.0 to 0.7.0!

@BDHarrington7 Thanks a lot man, you've done some great enlightening regarding switching those tags

@PitaJ said in Weird nodebb 502 bad gateway:

at version of NodeBB do you have?

currently running 1.0.3
After making backups, I ran the ./nodebb upgrade which did some stuff but the problem was still there and I rollebacked and decided to run it via forever.
just wondering why it would not work the way that it did for 2 years

Hi there,
I'm having the same problem and it just happened after a power outage.
When I invoke ./nodebb start nothing really happens but when I run ./nodebb dev or node loader.js --no-daemon --no-silent it works like a charm
it's also working fine with forever start app.js and the only problem seems to be the ./nodebb start.
p.s. logfiles are empty, all permissions are correct and nothing has really changed.
cheers

I think I wasn't logged in but as I told you, the website was not functional at all! even the HTML tags was not properly rendered(inspected using CTRL+U).
Now I've tried what you said and again failed with the same error message(NodeBB Upgrade could not complete, as your database schema is too far outdated). Here's what I did:

$ git checkout tags/v0.6.1
$ ./nodebb upgrade 
After upgrade, I've seen some green notice regarding the database schema update and everything went smoothly.
$ ./nodebb start
And of course started and working like a charm

Then I stopped the nodebb using :
$ ./nodebb stop

After that, I've tried to checkout 7 branch using:
$ git checkout tags/v0.7.0 and I got error regarding the tags(and I think it's normal because my nodebb is running on 0.6.0 branch and doesn't know about 0.7.0 which is actually in future)

So I ran:
$ git fetch
In order to get the latest commits/branches

Then I successfully switched to 0.7.0 branch using:
$ git checkout tags/v0.7.0

After that I tried to upgrade
./nodebb upgrade
Oops, database schema outdated bla bla bla and that's what I've got in the end.

@BDHarrington7 Thanks for your reply.
I have two VMs, one of them is production and another one is for test/experiment and the source code is 100% identical between these two machines.(even though once I tried it on production server to make sure it's not sync/copy problem between two machines.)
Actually I've tried many different methods and my forum is just a vanilla one without any modification(except favicon) so I think it's not normal to have conflict with 12-20 files only in the base code.
I'm not sure but I think I've tried this method(the last time) and everything went smoothly until I opened my forum and saw absolutely no content! Only the top menu and footer was there. No user, no post, nothing at all. I'll try again and I'll inform you as soon as I can work with that box.
and about the version, you're right but you should know how it's awful when you feel stuck..
Thanks again, I'll do it ASAP and inform you

I think I should ask my question in another way:
"Is there anybody out there who has successfully upgraded 0.6.0 to 0.7.0+ ?"
I'm just stuck in this version and can't do anything right now, except creating a new website from scratch and saying a big FU to all users and their posts and reputation!
Perhaps someone is interested in this problem?
I know it's a "community-driven" project and I ain't got no premium subscription or something, but seriously guys, isn't 15 day enough for getting at least a "dude, it's your problem! I've upgraded my forum and it's working."?

I think now it's time to /BUMP

@ffmad yeah, the DB is just fine and when I start another nodejs stance(yet another directory which is v.0.6.0) it's okay.
Also I'm wondering how the upgrade process was success on the DB!

@ffmad my bad about git fetch but after doing it the way that you said, I just got an absolutely empty board! not even basic example posts there!
