No usable key algorithm for matching kex algorithms
Hello!
I try connect to vm thru teleport(goteleport.com)
On connect to vm i see error

How add algorithms?
Hello,
The following algorithms you mentioned can be added under File > Options > Types > Sessions > Terminal > Algorithm Support. The will be found under the "Host key" tab:
