Thanks a lot guys for solving this issue. I had it with Cloudways. The last code works nicely, can you release the updated 2020.0.1 on nuget?
ps: I owe you a beer @drieseng

We are also seeing this issue with certain builds of OpenSSH. I would like to second @slim16165's suggestion to release a build with this fix.

[drieseng]

Sorry guys, I don't have a lot of spare cycles. I hope to find time this weekend.

Release 2020.0.1 is now available.
