Error 401

[Larry Hair]

At every startup.

Activated version 13.8.2.140, on Windows 11 Pro.

S/N: got me here

Logged in "Upper Right"

The only possible solution that I have seen thus are was to change password.......Did that and it went away for exactly 1 day and can back!

Seams to have been going on through several versions that I can see....... Considering a Patch any time soon???? (Within your system)

Thank you for reaching out through our Community Forums!

I noticed that you are running an old build of Nitro PDF Pro 13. The latest build at this point is on 13.70.x.x and I recommend updating to this build.
You can find the installer for the latest build of version 13 from the link below:

https://www.gonitro.com/product-details/downloads - click the 'Download Nitro Pro 13' link.

To update, simply run the installer and it will automatically update your installation to the latest build. 
When done, please observe if the 401 error persists. If it does, please do the following:

1. Open your Nitro PDF Pro then close the 401 error message if it shows up. 
2. At the top right, click the Logout then close Nitro Pro.
3. Open Nitro PDF Pro then click the Login button and log in using your Nitro Sign account. 

Kind regards,

Holy cow!  That IS shockingly out of date.  However, Downloaded and ran the install to get a Nitro Pro Setup Wizard has failed.

Also, Deactivated, Unistalled, Rebooted and retried installation.  Same result.

Thanks for the reply, any other suggestions?

Hi @Larry Hair 

Please try to install using the offline MSI installer. Please refer to the download links below:

64bit - https://downloads.gonitro.com/professional_13.70.2.40/en/retail/nitro_pro13_ba_x64.msi 
32bit - https://downloads.gonitro.com/professional_13.70.2.40/en/retail/nitro_pro13_ba_x86.msi

To know if you have 32-bit or 64-bit, please refer to this article:

After the installation, apply again the steps to resolve the 401 error.

Kind regards,

Thanks Raymond,

I actually go it to go yesterday by using an older nitro_pro13_ba_x64.msi that I had downloaded back in Dec of 2019,  (version unknown) it had me turning off various things along the course of the install (which I did not log.....) but it finally got all of the way thru, immediately after that the above 13.70.4.50 (exe) just worked without a hitch, so long way around the bush.  It's now at v13.70.4.50 and so far, the 401 Error appears to have been resolved. (Hopefully, this version comes with an "auto update"???)

I am also certain that your (msi) suggestion would have given me the same result in the end.  I will take this moment to replace my 2019 version on file.

 

Thank you!

Larry

Hi @Reymund Oyong,

I have the latest build (13.9.1.155), but this error started bugging me since early this week. What do we do?

Thanks,

I will take your advice, bu,t first, I must register my disgust at having to struggle to deal with a program that, until the last two months or so, worked quite well.

I strongly suspect that something went terribly wrong at headquarters, i.e., you either lost key programmers or you lost key managers or a combination of the two.  What's particularly exasperating is that you seem to anxious to resolve matters (laudable), but you don't seem being professionally transparent when it comes to letting us know what's going on.  How very, very Trumpesque.

Whatever happens, you should give those of us your Nitro PDF Pro 13 problems afflict a free upgrade to Nitro PDF Pro 14, assuming the "fixes" you suggest actually work.

Same problem here with Nitro Pro 12.16.9.574

What's the fix?

I am running what I believe is the current version 13.9.1.155 and I am getting the message 'An error has occurred within our system.  Please try again or contact support if this error persists.  (Error 401)' multiple times a day.
How do you contact support, I have been going round in a loop and all I can get are 'User Guide, Knowledgebase, and Community Forum'  As a paying customer I think that I should be entitled to official Nitro support.

I am tired of signing out and signing in, and even changing my password, with no change to the situation.

I have always relied on Nitro for my pdf needs but I'm seriously considering looking for another option.  Life is too short to waste it on software that does not appear to b fit for ourpose.
