Problems with REST API and asynchronus ucs creation

Tried a non task ucs save, and it also failed after sitting a while waiting on a response. Looks like support is my only hope.

❯ curl -k -u apiadmin:<redacted> -H "Content-Type: \
application/json" -X POST -d \
'{
"command": "save",
"name": "myUcs"
}' \

I can see it started, but didn't make it as far as the task request did.  It didn't get zipped up

Tried it from tmsh, just in case something was majorly broken :

(cfg-sync In Sync)(Active)(/Common)(tmos)# save sys ucs test_tmsh

Seeing the same TimeoutException errors from the non-task request as well

Thank you for taking a look with me, I appreciate it.
