Local server starts but I cant login

Solved
1

I lost my old computer. It got shocked with lightning strike. Very exciting.

So I decided to use Linux MINT as my new platform. The install went as easy as could be expected. The server started and I opened the ports on the router. I went to the admin web portal and it opened. I attempted to login but that is were I am stuck. I set the server.properties
admin.email=admin@blynk.cc
admin.pass=admin

Not sure why this does not work…

I also tried to login via the blynk app on my phone without any luck,

Any help will be appreciated.

Here is a copy of the log

I also set the rules for the firewall as follows.

sudo ufw allow 9443
sudo ufw allow 8080
sudo ufw allow 8443
sudo ufw allow 80
sudo ufw allow 443

I also tried it with the firewall disabled

There was no change.

Guess I am on my own,

Hi Mike, you lost me at …

I’m afraid :thinking:

My only suggestion would be to ensure that your server.properties file contains this line:

allowed.administrator.ips=0.0.0.0/0,::/0

to ensure that the admin can log in from any IP address.

Pete.

Well, it’s the holiday season! :slight_smile:

I’m a kind of guy that like my logs neat and clean, without errors and warnings. Pete might not agree with me, but I would fix the certificate issues first. If nothing else, to rule them out!

In a recent post @PeteKnight said something worth mentioning again*:

That file has 45 parameters in it, and you’ve chosen to incorporate 7 of them into your server.properties file.
Is there any logical process that you followed when choosing to omit the other 38 entries, and don’t you think that this may have a bearing on your inability to access the admin portal?

So, what does your server.properties looks like?

*Pete says many things worth repeating, all the time!

Looks like a standard configuration… Can’t really see any big problems! :face_with_raised_eyebrow:

Leave this parameter blank. Don’t know if it will do any good, but just in case.

I’m kinda out off ideas… All that’s left is your certs.

Anyhow, happy new year!

8

tried it both ways

9

Are you restarting the Blynk server after each change? I think the server.properties file is only read when the server starts-up.

My listen.address is also blank…

listen.address=

Pete.

10

Yes I exit and restart the server.
I now have the listen address empty. But there is no change that I can detect.

So what do you actually see on screen when you attempt to log in to the admin panel via the browser?

Pete.

no message

Okay, I’ve changed my logging level to match yours. If i try to log-in with the wrong credentials then I get pretty-much the same result as you…

TRACE- Initialized admin pipeline. [SslHandler#0, HttpsServerCodec, HttpsServerKeepAlive, HttpsObjectAggregator, HttpChunkedWrite, HttpUrlMapper, UploadHandler#0, OTAHandler#0, AdminAuthHandler#0, AuthCookieHandler#0, CookieBasedUrlReWriterHandler#0, StaticFileHandler#0, OTALogic#0, UsersLogic#0, StatsLogic#0, ConfigsLogic#0, HardwareStatsLogic#0, HttpAPILogic#0, NoMatchHandler#0, DefaultChannelPipeline$TailContext#0]
DEBUG- POST : /admin/login
TRACE- Mapping from /admin to /admin
TRACE- Is unpacked.

With the correct credentials I get an extra line that says “DEBUG- Admin login is successful. Redirecting to /admin” …

TRACE- Initialized admin pipeline. [SslHandler#0, HttpsServerCodec, HttpsServerKeepAlive, HttpsObjectAggregator, HttpChunkedWrite, HttpUrlMapper, UploadHandler#0, OTAHandler#0, AdminAuthHandler#0, AuthCookieHandler#0, CookieBasedUrlReWriterHandler#0, StaticFileHandler#0, OTALogic#0, UsersLogic#0, StatsLogic#0, ConfigsLogic#0, HardwareStatsLogic#0, HttpAPILogic#0, NoMatchHandler#0, DefaultChannelPipeline$TailContext#0]
DEBUG- POST : /admin/login
DEBUG- Admin login is successful. Redirecting to /admin
TRACE- Mapping from /admin to /admin
TRACE- Is unpacked.

It seems that the credentials aren’t being recognised as valid.

Is there any possibility that your server.credentials file isn’t actually being recognised, or that you have another one somewhere (maybe hidden) that is being used, with different credentials in it?

I guess one way to test this is to change your logging level from trace to debug and re-start your server then check the logs. If the TRACE entries disappear and you only have INFO and DEBUG entries then what you think is the correct server.properties file is being used.

You could then try to change the credentials in the server.properties file to something other than admin@blynk.cc/admin

Pete.

Okay I will give it a try

Thanks

Okay, so it is reading the correct server.properties file.
Now try changing the credentials to something different and see if that works.
