Overview
When connecting to M-Files with the M-Files Mobile app, you may get an error saying "No Vaults found". When you open the error details, it says "java.security.cert.CertPathValidatorException: Trust anchor for certification path not found".
Solution
This error is usually caused either by a self-signed SSL certificate or a missing intermediate certificate. Make sure to use an SSL certificate signed by a trusted third-party and check that you have all the intermediate certificates installed on your IIS server.
You can use online SSL diagnostic tools, like https://www.digicert.com/help/ or https://www.ssllabs.com/ssltest/ to check whether your certificate is fully compliant and properly installed.
It is ok to use a wildcard certificate (issued to *.company.com), as long as it is signed by a trusted third-party, and the trust chain is unbroken (all intermediate certificates are included).
For more information about certificate-related issues with the M-Files Android app, refer to Android SSL Certificate errors.
