Connect Failed not same with APP and remoteExample

[tt2nn]

Hi：
When i used OpenVPN Connected APP to connect vpn. get faile and disconnect, I get error log like:

LOG: Transport Error: mbed TLS: SSL read error : X509 - Certificate verification failed, e.g. CRL, CA or signature check failed
Setting LAST_EVENT=CERT_VERIFY_FAIL
EVENT: CERT_VERIFY_FAIL info='mbed TLS: SSL read error : X509 - Certificate verification failed, e.g. CRL, CA or signature check failed'
Broadcasting LAST_EVENT=CERT_VERIFY_FAIL
eceived EVENT=DISCONNECTED

Then i used remoteExample to connect same vpn. always reconnecting, I get error log like:

MANAGEMENT: >STATE:1662409833,WAIT,,,,,,
MANAGEMENT: >STATE:1662409833,AUTH,,,,,,
VERIFY ERROR: depth=1, error=certificate is not yet valid: CN=DO-VPN CA, serial=566640800809079469109513829525409701738862451438

There is a problem with the certificate or some of your time on the phone or server
