We are only able to generate "legacy" addresses that begin with a "1". This is a long standing problem generating new addresses using bitcoind and has persisted through a few recent versions of bitcoin core.
This might be a possible bug in bitcoind 64-bit linux.
We are currently running core 19.1 taken from here: https://bitcoincore.org/bin/bitcoin-core-0.19.1/
And our linux version is: Ubuntu 18.04.3 LTS x86_64
We have "addresstype=bech32" set in our bitcoin.conf.
Has anyone else seen this problem before?
Here is our bitcoin.conf:
addnode=**.***.***.*** server=1 rpcport=**** walletnotify=/btc_notify.sh %s # OpenSSL settings used when rpcssl=1 rpcsslciphers=TLSv1+HIGH:!SSLv2:!aNULL:!eNULL:!AH:!3DES:@STRENGTH rpcsslcertificatechainfile=server.cert rpcsslprivatekeyfile=server.pem gen=0 keypool=100 paytxfee=0.00005000 addresstype=bech32
And here is an example of how the problem manifests itself:
