Problem with ERR_CERT_AUTHORITY_INVALID on mobile client

[darnasii]

Hello,
I'm having trouble configuring mobile apps for users. Attempts to configure them result in an error:

[error] | 9:09:19 11ms | Enrollment via QR start failed!
DioException [unknown]: null
Error: NetworkClientException: Exception in CronetUrlRequest: net::ERR_CERT_AUTHORITY_INVALID, ErrorCode=11, InternalErrorCode=-202, Retryable=false, uri=https://gateway.internetunion.pl/api/v1/enrollment/start, errorCode=11, cronetInternalErrorCode=-202, immediatelyRetryable=false

Defguard manages the certificates; there is no reverse proxy. The certificates are valid.

Solved. Needed to issue new cert for Edge via GUI.
