io.UnsupportedOperation: File or stream is not seekable. with python 3.6 #3
Description
On almalinux 8.x w/ the python36-3.6.8-38.module_el8.5.0+2569+5c5719bc.x86_64 package i get this error:
/usr/local/bin/negotiator-guest -vvv -d

this looks like maybe related to a python bug:
https://bugs.python.org/issue20074
if i use python 2.7 on the same guest, i can start the daemon w/o issue and the negotiator-guest daemon and use the client w/o issue.
