Found a website with the errorcode and "Schlüsselbund" issues, but the outgoing link to the apple discussion forum is not working.

It is an issue with the keyring store, could not been read or add anything.

And here is a link to the german apple forum with some troubleshooting tips for the keychain

and here some more

Try to backup/export the keystore and delete it afterwards.
Then recreate it and try to import the certificate

Hope this helps

Screenshots from License and Update Screen and certificate

Scrennshots

I also have another certificate with "*.cer" instead of "*.crt", but when I tried to make an upload there was a message that this is not possible at the moment.

I found two certificates in the keyrings but I'm not able to delete them and try it again. (see in keyrings.pdf)

No visible error in the attached screenshots..
So please go through the websites I posted, regarding the keyring issue in MacOS...

As I don't have an Mac, I am not able to check this issue any deeper as I've already done.

Good luck
Cheers
Sven

You're welcome 🙂

Hello everybody,

today I did a clean install of eBlocker 2.4.5 for testing purpose. With MacOS Catalina (15.4) I had the same problem (though selecting 24 months); see attached hardcopy.

The solution is very simple: You may not import the certificate as described in the docs you must double click on the file. Then it gets automatically imported

Seems to me like a bug in the keychain import...

as described in the docs

Which docs are you referring too? (It‘s quite some docu chaos meanwhile. Sorry.)

Can you help with the update changes as I‘m on Windows...?

@Random Yes, of course I can help. I fond two sources for the "import" method: https://eblocker.github.io/help/en-us/360002344313.html and the built in wizard of eBlocker UI which shows me appropriate steps if the certificate is not found. By the way, I am sure this wizard is a great help for "normal" users. Congratulations!

Of course, I can't tell you if older MacOS versions were able to import the certificate by double click. Maybe I should try the import with more different preconditions?

I had also the problem with activating the HTTPS support on the dashboard, because the new 24 month certificate was not accepted. Please find enclosed a short note with a bunch of screenshots. I hope this may help although it's in German. 

Apparently my pdf file (368KB) was not received by you. here's another try.

@adaeweritzt-online-de You can post screenshots and a deepl translation directly in the forum. PDF can not be indexed by our search function and German is discouraged as it discriminates non German speakers.

We‘d love to hear your experiences and would like to encourage you to post straight in the forum (not in external documents) - and in English only please.

THX!
