[James Poff]

when i want to backup cucm configs with DRS, this error happens:
"WARNING: Unable to contact server. Master or Local Agent could be down"

how can i fix this issue?

Hi dear @James Poff 

this issue maybe probably related with IPSEC certificate on your CUCM..
it's maybe has been expired & you must Re-Generate that..

check this URL >> section Re-Generate IPSEC >>
https://community.cisco.com/t5/collaboration-knowledge-base/cisco-uc-certificates-renewal-guide/ta-p/4077131#toc-hId-1467313498

remember that you must do that on all cluster nodes (cucm-pub + cucm-sub + cup-pub + cup-sub + etc..)

thanks
i regenerated ipsec & drs is now taking backup completely
