Zcashd DNS err

we have started zcash node in our cloud provider server , After configuring the node to run on mainnet we saw the following logs. we wanted to know weather our node as started
properly and If not what could be the issue ?

This script is no longer needed for users of zcashd. Proving system
parameters now only need to be downloaded in order to spend Sprout funds.
Parameters for other pools are bundled with the zcashd binary or generated
when it is run, and do not need to be downloaded or stored separately.
This script is deprecated and will be removed in a future release.

If you need to spend Sprout funds, download the Sprout parameter file from
https://download.z.cash/downloads/sprout-groth16.params and put it at

Find our configuration file below;-
rpcuser=myrpcuser # Replace with your desired RPC username
rpcpassword=myrpcpassword # Replace with your desired RPC password
rpcport=8232 # Port for RPC connections

Any sort of help or guidance is appreciated, Thank You !!

Its complaining about the DNS seeder :thinking:

are you running the node is regtest by any chance :question:
if you need mainnet :
add these lines to your config:

I wonder if it’s invoking regtest because it’s ‘bind’-ing on the local port, that might need to be ‘rpcbind’, or ‘rpcallow’. ‘bind’, I believe, is for the node traffic and not the rpc. I dont think ‘rpcconnect’ is a valid flag.

Thanks for supports, I have tried this one also , manual installation its working fine. while trying to run in docker I am facing the same issue

post the docker file if you can and how you run it.
