WARN [09-21|09:10:19.868] StartRPC failed: listen tcp IP:9500: bind: cannot assign requested address port=9000 ip=IP funcName=main.main funcFile=main.go funcLine=491

It is running the latest version of node
LD_LIBRARY_PATH=. ./harmony -version Harmony (C) 2019. harmony, version v4662-pangaea-20190920.0-0-gc2324c41 (jenkins@ 2019-09-21T06:31:36+0000)

Ports are open and accessible. no firewall running. no issues with traceroute or ping

Had the same as Mirror Mirage, this is from zerolog:

{"level":"warn","port":"9000","ip":"93.103.119.129","error":"[SYNC] cannot find peers using DNS name "s3.p.hmny.io": lookup s3.p.hmny.io on 127.0.1.1:53: server misbehaving","shard_id":3,"caller":"/mnt/jenkins/workspace/harmony-release/harmony/node/node_syncing.go:214","time":"2019-09-21T12:16:21.510251813+02:00","message":"cannot retrieve syncing peers"}

solved it either by setting port 9500 or changing DNS settings to Google ones, i am not completely sure what did the trick in the end

EDIT: note that this is a personal home server, on which all previous versions of pangaea and mainnet worked normally, until this last one
