Read Error [Solved]

[b.huijskes]

Hi!

I’ve started experiencing problems when opening models from networks other than the company network when trying to connect to ACC through the integration.
When I work at our office, the error magically disappears and everything works like it should.

Before opening the model, I am able to connect to ACC and navigate to the right folder / model (implying that the connection itself works, else I would not show me the ACC folder structure).
Only upon selecting the model and trying to open it, will it displays this error. I am running the latest Solibri version (25.3.1.59) on a Windows 11 laptop.
Reading through the error code, I can’t really pin down what the cause might be. Is anyone having similar issues, or might know in what direction the solution might be?

Application build number: 25.3.1.59
Model is saved with build number: ?

[Matti]

PKIX in the error log is often related to SSL certificates and firewalls.

Try adding this line to “C:\Program Files\Solibri\SOLIBRI\Solibri.vmoptions”

-Djavax.net.ssl.trustStoreType=WINDOWS-ROOT

There is also another (harder) way to solve this by adding your certificate to Java keystore.

@Matti Thanks you! This helped. I’ll close the topic.
