Connection Error - 'winiomwin' - encryption error

[ChrisR009]

Hi. Having difficulty connecting on 'winiomwin' configuration. Receiving the following errors which appear to be related to encryption (AES) mismatch between saspy and server .

We believe we have the configuration file correct. Any direction on how to resolve this would be appreciated.

Thankyou.

Using

• Python 3.9.7
• saspy 3.7.5
• JRE 7 (java version "1.7.0_80")
• SAS 9.4 m4
• Windows Client
• Windows Server

Hey @ChrisR009 would you mind moving this to an Issue? Problems and requests for help should be opened as an Issue, as opposed to being here in this discussions channel. That way when people search for similar problem/answers they will find them.
I think the solution should be simple. Your Workspace server is configured w/ AES encryption. So to connect, you either need the encryption jars added to the iomclient directory in your saspy install (https://sassoftware.github.io/saspy/configuration.html#attn-as-of-saspy-version-3-3-3-the-classpath-is-no-longer-required), or you just need to upgrade Java to the current Java 8 which has support for this in it (then you don't need the jars).

BTW, I though I'd documented this error previously in the troubleshooting guide, but I hadn't. So, I just added it there; see number 8 here: https://sassoftware.github.io/saspy/troubleshooting.html#iom-specific-errors
Sorry that wasn't there for you when you hit this, but it there now, at least.
