Multiple VMs failing with Soap fault detected, Query problem, resolve themselves in next run

Hi All,

We have multiple VMs in our environment running on Avamar 19.3 , VMware VixDiskLib (6.7) Release build-13015725. They are randomly failing with the below error:

2020-11-30 11:00:49 avvcbimage Warning <16004>: Soap fault detected, Query problem, Msg:'SOAP 1.1 fault: SOAP-ENV:Client [no subcode] "Temporary failure in name resolution" Detail: getaddrinfo failed in tcp_connect()

2020-11-30 11:00:49 avvcbimage Error <0000>: [IMG0009] Create Snapshot: snapshot creation/pre-script/post-script failed.

The backup gets completed on the next run. It seems like a DNS issue but I am not sure how to go about resolving it. Looking for help here, please let me know what to check here.

Thanks in Advance.
