I've set up an arangodb cluster within google cloud kubernetes. When I try to call methods using ArangoJS, it randomly throws following error.

Error: read ECONNRESET at exports._errnoException (util.js:1020:11) at TLSWrap.onread (net.js:580:26) code: 'ECONNRESET', errno: 'ECONNRESET', syscall: 'read',

Also within the error there's a line with

authorizationError: 'SELF_SIGNED_CERT_IN_CHAIN',

It doesn't seems to occur when the server is already reading from the database, but when it reads from database after some idle period. (There's a load balancer in-between also)

Can anyone help me here?
