Hello everyone,

We are currently facing a weird issue in production with the DelimitedFile Connector using SFTP to aggregate CSVs.

Everything seems to work as expected, but randomly, we start getting this error :

net.schmizz.sshj.transport.TransportException: Unable to reach a settlement: and [blowfish-cbc, aes128-ctr, aes192-ctr, aes256-ctr, 3des-cbc, aes128-cbc, aes192-cbc, aes256-cbc]

and the only way to fix this is by rebooting the server facing the issue. This can occurs on any of our 8 servers randomly.

We are totally unable to reproduce this in non-production (Both prod and non-prod are on the 8.2p1 version)

It is hard to know if it could be related with Libraries conflicts (like one of our custom connector is dependant on another version of BouncyCastle) or if this could be something related with the servers themself. Does anyone faced a similar issue in the past and was able to resolve this ?

Hi @jplefebvre2,
This looks to be an infra server issue.
Please find more info on the stackoverfliw page.

net.schmizz.sshj.transport.TransportException: Unable to reach a settlement

You can create a monitor to check test connection ssh connection from task server to sftp server and create an alert in this eay you willl find out what time its causing the issue then you can report to the infra team.

Its was a conflict with the BouncyCastle library used by a custom connector. Setting that library to the same version as the one present in lib-connector (jdk15on-164) resolved the issue.
