Selection of gateways for reconnection upon detection of reachability issues with backend resources

A system for selecting a device via which a client is to connect to a server, comprising:

• a client having one or more processors coupled with memory, configured to:
• identify a server and a plurality of devices intermediary to the client and the server via one of which the client is authenticated to connect to access the server using a certificate;
• detect that the server is unreachable from the client authenticated to use a first connection via a first device of the plurality of devices using the certificate;
• select, responsive to detecting that the server is unreachable, a second device of the plurality of devices via which the client is to access the server;
• and
• authenticate, using the certificate used to authenticate with the first device, the client to establish a second connection with the second device to access the server.

A non-transitory computer readable medium storing program instructions for causing one or more processors to:

• identify a server and a plurality of devices intermediary to the client and the server via one of which the client is authenticated to connect to access the server using a certificate;
• detect that the server is unreachable from the client authenticated to use a first connection via a first device of the plurality of devices using the certificate;
• select, responsive to detecting that the server is unreachable, a second device of the plurality of devices via which the client is to access the server;
• and
• authenticate, using the certificate used to authenticate with the first device, the client to establish a second connection with the second device to access the server.
