Desktop App is endless "verifying access token" when opening my cloud projects

Ingo · October 15, 2024, 8:51am

Today I’m not able to access my project which is stored in the cloud. When trying to open the project it didn’t work. The screen shows “You access will expire in…” and I also restarted the App some times. But it always show the “verifying access token” with the rotating logo.

Can you please post the contents of the log when it happens? You can find the log with Help > View log (make sure to select and copy all the contents) or in the file ganttproject.log that sits in your home directory.

And it still get stuck at the same point.

DmitryBarashev · October 15, 2024, 12:30pm

The log indicates that your Java Runtime can’t validate the ganttproject.cloud certificate. Possible reasons:

The certificate on ganttproject.cloud is broken (does not seem to be the case, I just’ve checked that the certificate is valid)
Your Java Runtime is missing the required certificates in the certificate chain
There’s a kind of man-in-the-middle attack, and someone is trying to route you to some other site that pretends to be ganttproject.cloud (this is basically what SSL certificate is meant to protect from)

Can you try installing GanttProject 3.3.3312 before we proceed further? It comes with the latest Java Runtime and possibly will help if the reason is 2)

Ingo · October 15, 2024, 12:47pm

Okay, will try this, but not before tomorrow. Thanks for your support.

Ingo · October 16, 2024, 6:55am

Okay, that’s weird… Since I couldn’t find the archive with 3.3.3312 I instead installed the latest one (ganttproject-3.2.3240.exe) and now have the 3.2.3230?!
Maybe of interest: I had both versions in the system and then deinstalled both and installed only the latest one again. Still the same situation/stuck at the access token check.
3. is unlikely since I also run it at home / my private network instead of the company network without any change (and with a different installation of the program).

Ingo · October 16, 2024, 6:58am

I also tried to open: dl.ganttproject.biz/updates/ganttproject-3.0.json with a browser and it worked fine. So it’s not generally blocked from company policies or such.

Ingo · October 16, 2024, 7:21am

Lost in the web… I somehow managed to find an old installation file. Retry now with 3.3.3312. Please wait…

still same situation…

DmitryBarashev · October 16, 2024, 11:00am

GanttProject 3.3.3312 is available from our web site: GanttProject - Download

Direct link: https://www.ganttproject.biz/dl/3.3.3312/win/exe

DmitryBarashev · October 16, 2024, 11:58am

I also tried to open: dl.ganttproject.biz/updates/ganttproject-3.0.json

This is the url where GanttProject fetches update metadata from. It is unrelated to GanttProject Cloud.
GanttProject Cloud requests are sent to https://ganttproject.cloud/

DmitryBarashev · October 16, 2024, 2:31pm

So, if updating Java Runtime did not help, and you are sure that it is not the issue in the network where you run then we can add the certificate to Java Runtime. This will most likely require Admin privileges on your computer.

The instructions are here: Mend.io Documentation

I have done the first part with extracting the certificate, so basically you need to download and install it using keytool utility. The certificate is attached.

You need to open terminal window (cmd.exe), change the directory using

cd C:\Program Files (x86)\GanttProject-3.3\runtime\lib\security

and run

keytool -import -noprompt -trustcacerts -alias http://ganttproject.cloud -file "C:\Users\E1392328\Download\ganttproject.cloud.crt.txt" -keystore cacerts

If it says that it can’t find keytool program, replace keytool with ..\..\bin\keytool (a relative path from lib\security to the Java executable files)
ganttproject.cloud.crt.txt (1.3 KB)

Ingo · October 18, 2024, 8:49am

maybe I made somewhere a mistake…
I followed the steps in mend.io and got the result:

c:\Program Files (x86)\GanttProject-3.3\runtime\lib\security>"C:\Program Files (x86)\GanttProject-3.3\runtime\bin\keytool.exe" -import -noprompt -trustcacerts -alias http://ganttproject.cloud -file "C:\Users\E1392328\Downloads\ganttproject.cloud.crt.txt" -keystore cacerts
Warning: use -cacerts option to access cacerts keystore
Enter keystore password:
Certificate was added to keystore

next step was to run both of your commands:

c:\Program Files (x86)\GanttProject-3.3\runtime\lib\security>"C:\Program Files (x86)\GanttProject-3.3\runtime\bin\keytool.exe" -import -noprompt -trustcacerts -alias http://ganttproject.cloud -file "C:\Users\E1392328\Downloads\ganttproject.cloud.crt.txt" -keystore cacerts
Warning: use -cacerts option to access cacerts keystore
Enter keystore password:
keytool error: java.lang.Exception: Certificate not imported, alias <http://ganttproject.cloud> already exists

The error still remains

DmitryBarashev · October 18, 2024, 4:21pm

Okay, maybe it needs the whole certificate chain? I exported the whole chain (attached), try importing it using the same commands, with different alias (e.g.

c:\Program Files (x86)\GanttProject-3.3\runtime\lib\security>"C:\Program Files (x86)\GanttProject-3.3\runtime\bin\keytool.exe" -import -noprompt -trustcacerts -alias http://ganttproject.cloud.chain -file "C:\Users\E1392328\Downloads\ganttproject.cloud.chain.txt" -keystore cacerts

ganttproject.cloud.chain.txt (3.1 KB)

There’s also a GUI program for viewing and modifying the certificates:

The KeyStore explorer allows for typing a host name (ganttproject.cloud) and importing the certificates, using Examine>Examine SSL
However, you need to make sure that you run the KeyStore explorer using the same Java Runtime that is used for GanttProject.

KeyStore shows me a valid certificate:

Entry Name=http://ganttproject.cloud
Algorithm=EC
KeySize=256
Certificate Expiry=12/22/2024 6:03:49 AM CET
Last Modified=10/18/2024 10:37:38 AM CEST
So I would say: Certificate is installed and functional. Guess what… it’s still the same error.
I will now install GanttProject on another PC to see if maybe our Firewalls are blocking it.
Is there a chance to completely remove GanttProject including certificates and Registry-entries. To start again from scratch? Maybe this is much better and more efficient?

GanttProject itself does not install any certificates. It is Java Runtime and probably Windows who are responsible for the certificates.

What KeyStore Explorer says if you ask to Examine > Examine SSL ganttproject.cloud? On my laptop the result Is as follows:
