Hello,

could you please check if localhost on your host is resolved to 127.0.0.1 or ::1?
You can use the following method to do that:

$ ping localhost -c1 -n
PING localhost(::1) 56 data bytes
64 bytes from ::1: icmp_seq=1 ttl=64 time=0.027 ms

Also, could you please check what is MongoDB bound to?

# netstat -nlput | grep -i mongo
tcp 0 0 127.0.0.1:27017 0.0.0.0:* LISTEN 2511/mongod 

If it listens on 0.0.0.0 (ipv4), and localhost resolvs to ::1 (ipv6), please explicitly specify 127.0.0.1:

# pmm-admin add mongodb --uri 127.0.0.1:27017
