Local Blynk Server - Login

Need Help With My Project
1

Hallo,
I have installed a local Blynk Server on my Synology NAS. Der Blynk Server is online and I can reach the website https://192.xxx.xxx.xxx:9443/admin in Firefox and Safari with MACOS.
When I “Use your Admin account to log in” and put the adress “admin@blynk.cc” in the field for email-Adress and the password (which was send via email to me) in the second field and I touch “sign in” my user email and pasword are cleared.

The same happened with an e-Mail from a new project, which I have created on the Blynk App.

No login is possible. What can I do to fix this problem?

Thank you for help
Mike

The default password for admin@blynk.cc is "admin`

If you’ve created another user, and received an email from your local server (which seems unlikely unless you’ve correctly configured a mail.properties file) then you need to be using that email address and password, provided that user has admin rights.

Pete;
I have mail.properties file configured correct and I have made a new account at gmail for the local Blynk Server. After installation I received an email with the user and the password “N…vi”.

The mentioned user and password “admin” did not work. The fields will be cleared after “Sign in”.

It must be an other problem in configuration or something else …

Thank you for help

Delete the .user files (located in /home/pi/Blynk/ if you’re using a Pi) and restart your server.
You should then be able to log-in to the admin console with admin@blynk.cc and admin

Pete,
I have written “I have installed a local Blynk Server on my Synology NAS” .
In the directory /Blynk I can find two users: admin@blynk.cc.Blynk.user and the second xxx@xxx.xx.Blynk.user from a new project via Blynk App.

Thank you for help
Mike

Quite right, I’d forgotten that by the time I got to replying to post #3, and reading/replying to a few other topics in the meantime.

Delete these files, then restart your server and log-in to the admin console with admin@blynk.cc and admin

Pete;
I have deleted the two users and restarted the Blynk Server via NAS. the same result after Login with admin@blynk.cc and PW admin. After Sign in the fields are empty.

Thank you for help

What does the `allowed.administrator.ips’ entry of your server.properties file say?

What browser are you using?

Pete.

Pete;
this is my file server.properties:

<#hardware mqtt port
hardware.mqtt.port=8440

#http, plain web sockets and plain hardware port
http.port=8080

#if this property is true csv download url will use port 80 and will ignore http.port
force.port.80.for.csv=false

#if this property is true redirect_command will use 80 port and will ignore http.port
force.port.80.for.redirect=true

#secured https, web sockets and app port
https.port=9443

#address to bind to. by default bounded to all interfaces
listen.address=

#by default server uses embedded in jar cert to simplify local server installation.
#WARNNING DO NOT USE THIS CERTIFICATES ON PRODUCTION OR IN WHERE ENVIRNOMENTS REAL SECURITY REQUIRED.>

This is the sample server.properties file…

Note that any changes require a restart of the server for them to be auctioned.

I use Firefox 90.0.2 or Safari Version 14.1.1 or Google Chrome Version 92.0.4515.107. In Chrome I could not open the Admin Page https://192.xxx.xxx.xxx:9443/admin because the website is not safe.

Pete,
I have changed my server.properties file against the original file https://github.com/Peterkn2001/blynk-server/blob/master/server/core/src/main/resources/server.properties

In that file I have set the PW to admin. Than I have uploaded the file to my NAS in /Blynk and I tested the Sign In. The result is the same. After input an Sign in the fields are empty.

Mike

Did you restart the server between these two steps?

Pete.

15

I have restart the Blynk Server on my NAS and the same problem is on Sign In.
Mike

16

I have restart the Synology NAS and start Blynk Server. The result ist no “Sign In”.

Mike

17

Is this a message that you see when attempting to log-in via the admin console, or somewhere else?

What do the server logs show when you try to log-in?

Pete.

18

This is my values for “allowed.administrator.ips=0.0.0.0/0” in the file server.properties.

Pete;

there is no solution for my local Blynk Server on NAS. Please give me a tipp where I can find new software for a local Blynk Server to reinstall it. This website is dead since some days: https://github.com/blynkkk/blynk-server

Thank you for help

From the fork of the code that I linked to earlier:

It might also be worth looking at what version of Java you are using and upgrading if possible.
If your device supports Java 11 then you should use that, along with the server-0.41.16.jar file.
If not, then you’ll need to use Java 8 with the server-0.41.16-java8.jar file.

And of course, the command line to launch the server will be different in each case.
