Question

Customer would like to add Linux-based NVR into VAST2 v2.7.0.5800 via openVPN but failed.
Customer made sure to input correct VAST2 Public IP(or DDNS) in Linux-based NVR and open required ports* in router for VAST2.
*Default API service port: 3443
 Default openVPN tunnel port:3939

Linux-based NVR setting Network > Service > CMS & iViewer > VAST2 remote connection.


However, VAST2 failed to add the substation via openVPN and will display the following log:

 

Answer

The problem only happens when adding substation via openVPN after upgrade to v2.7.
VAST2 v2.6(included and before version) adds substation via openVPN  then  upgrade VAST2 to  v2.7  => Success!
VAST2 v2.6(include and before version) upgrade to v2.7 then add substation via openVPN => Fail!

The root cause is this issue is a parsing error in the request header sent from the NVR to the VAST2.
This issue will be fixed in VAST2 version 2.8 which will be released to official website on end of May, 2020.
You could download v2.8.0.6500 from ftp://fae:[e-mail]/software/VAST2/VAST_2_8_0_6500_x64_setup.exe
