Failed to login to appliance for data synchronization

03/26/2020 1128 13286

DESCRIPTION:

When using the "Login to unit" function in GMS, the following error occurs:

“Failed to login to appliance for data synchronization”

CAUSE:
This is caused by a security function of the UTM firmware blocking the login attempt due to the usage of TLS 1.0 or other security mechanics are in place, like the RC4 cipher suit.

RESOLUTION:

Depending on the firmware being used, the following can be done:

Step 1: If you are using any of the following firmwares please contact Technical Support and request the corresponding HotFix

•             6.1.1.10-4n--HF160194-1n

•             6.2.2.2-19n--HF160194-8n

•             5.8.4.0-7o-HF160194-2o

•             5.9.1.1-39o--HF162292_6o

Step 2: If Step 1 is not applicable, login to the affected firewall and go to the diag.html website:

Note: A reboot is required when dealing with cryptographic material.

Search for the option "Disable TLS v1.0", uncheck this.

Search for the option "Use RC4 cipher suit", uncheck this.

Step 3: As a workaround you can activate the HTTPS redirect on the interface of the firewall which is used by GMS/Analyzer to communicate with the unit. Then you can use the option in GMS/Analyzer “Login using HTTP”.
