Startup Issue : java.security.cert.X509 error
-
I’m suddenly getting this error when I try to run Solibri Office - tried uninstalling and reinstalling the latest version but no dice… anyone got any ideas how to fix this? It still runs okay on other PCs in the office…

-
@celineman @keithwilkinson Glad to hear all is fine now!
We’re still investigating and so far the issue seems to point towards Cloudflare since this issue disappeared after they did a maintenance break earlier today, only for the UK.
Despite this, we apologise for the inconvenience. -
Weirdly, I’m glad it’s not just me…
-
Yes, the problem is still there. But not on all PCs.
-
Our support got similar error reports mostly from UK.
Are you using Mac or Windows?
Locating in UK? -
In case of Windows, try adding this option to “C:\Program Files\Solibri\SOLIBRI\Solibri.vmoptions”
-Djavax.net.ssl.trustStoreType=WINDOWS-ROOT -
@celineman did you try that option?

Hi, tried adding that here but no joy. I’m also UK-based and using Windows.

Just to check if you are having some firewall or similar that could affect:
- Open https://api.solibri.com/ to you browser (Chrome)
- Click the icon in front of the address bar
- Click “Connection is Secure”
- Click “Certifcate is valid” (In Edge browser there is a Certificate icon instead)
- Check that certifcate matches: Cloudflare, Inc. and public key 80d1db0dd47ad24ac24c05fe19273a1a4b39977563a3f9a69ae970b53a1b44fa

@Matti-Kannala
That all seems to match here.

Was this from a PC where the Solibri is not starting?
-
@Matti-Kannala Yes, this is the machine were Solibri isn’t starting.

This is what I got
- Open https://api.solibri.com/ to you browser (Chrome)
- Click the icon in front of the address bar
- Click “Connection is Secure”
- Click “Certifcate is valid” (In Edge browser there is a Certificate icon instead)
In that page:
- Click the Details:
- Click Export… and save the cert to local disk
- Click Windows key
- Type “CMD”
- Right Click the Command Prompt icon appearing
- Click “Run as Administrator”
- Run command
“C:\Program Files\Solibri\SOLIBRI\jre\bin\keytool.exe” -import -noprompt -cacerts -alias api.solibri.com -file “<path to the file exported file>” - Type “changeit”
-
@Matti-Kannala Tried this along with a couple of other suggestions from tech support but still the same issue.
-
any other ideas on this?
