[ RESOLVED ] Can't connect to license server and can't update

Recommended Posts


Here's the sequence of what has happened so far:

  1. Opened Malwarebytes to find out it had logged out of my Premium account;
  2. Tried to log in, returning the "can't connect to license server" error;
  3. Unninstalled Bonjour -> Didn't fix the issue;
  4. Used mb-support tool to repair windows network -> Didn't fix the issue;
  5. Used mb-support tool to remove all Malwarebytes;
  6. Installed an offline version (4.5.0) because the normal one kept getting stuck at "Installing 5%...";
  7. Try to update to newer versions -> Network Error: Unable to contact update server;
  8. Try to log in to my Premium account -> Can't connect to license server;
  9. Used mb-support tool to generate log files -> See attach

My Internet works, otherwise I wouldn't be typing this topic, and I've also restarted my router.

Can someone help me?

Thank you.

Hello @corvowas and :welcome:

Thank you for the fine description of the system's issue and the included MBST-grab.

Through no fault of your own, and for an unknown reason, MBST failed to generate/include FRST logs also which assists in deeper analysis.

Please download the Farbar Recovery Scan Tool and save it to your desktop.

Note: You need to run the version compatible with your system. You can check here if you're not sure if your computer is 32-bit or 64-bit

  1. Double-click to run it. When the tool opens, click Yes to disclaimer.
  2. Press the Scan button.
  3. It will make a log (FRST.txt) in the same directory the tool is run. Please attach it to your reply.
  4. The first time the tool is run, it also makes another log (Addition.txt). If you've, run the tool before you need to place a check mark here each time
  5. Please attach the Additions.txt log to your reply as well.
  6. On your next reply, you should be attaching FRST.txt and Additions.txt to your post.

Thank you.

Hello @corvowas   I am moving your Thread-topic so that I can provide one to one help.

The first suggestion I have is:  To do one Windows RESTART  on your system.  It had some pending operations to do that need a Restart.

After that is done, I would like a first simple report for review.

This next is just a report to check on some Windows services  

Download   Farbar's Service Scanner utility

and Save to your Desktop.

Right-Click on fss.exe and select Run As Administrator.

Answer Yes to ok when prompted.

If your firewall then puts out a prompt, again, allow it to run.

Once FSS is on-screen, be sure the following items are check-marked:

  • Internet Services
    Windows Firewall
    System Restore
    Security Center/Action Center
    Windows Update
    Windows Defender
    Other services


Click on "Scan".

It will create a log (FSS.txt) in the same directory the tool is run.   Please attach that file.

@Maurice Naggar excuse the intrusion,

@corvowas is located in Portugal.

The following should fix the issue.

Please try the following. Open an Elevated Admin command prompt and copy / paste the following and press the Enter key. You should get a success message.

reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters" /v "DisabledComponents" /t REG_DWORD /d 32 /f

Then restart the computer and try installing and activating the program again.

This will set the IP preference to use IPV4 instead of IPV6 as recommended by Microsoft without actually disabling IPV6


Let me know if that helps correct the issue for you.

Hello,@Maurice Naggar

I have run the scan with all items checked and the FSS.txt file is attached.


Hello, @Porthos

I entered the command and it returned a successful message. I restarted my computer but, this time, Malwarebytes Setup is stuck at "Installing... 19%" and the program itself is (Not Responding). I even left it alone for 30 minutes so it could start responding but no luck.


Thank you all for helping me.

I'm sorry for the double reply.

Looks like I should have been 1 minute more patient, because as I hit "Submit Reply" on my last message here, the (Not Responding) setup fixed itself and it ended the installation.

I have successfully logged in and performed a "Check for Updates" without any errors.

Feels good to have the Premium Protection back on!

@Porthos's command fixed my issue, I believe.


I want to thank @1PW, @Maurice Naggar and @Porthos for being so helpful.

All the best to you.
