Hi, thank you for your message. I thought I had the latest version.
I installed the new version but it doesn't work either...

[schollz]

room not ready means the sender hasn't initiated. did you initiate sender first?

[Dominique63]

I'm not sure I understand.
I did this:
dominique@dominique-AcerAspire:~$ croc send dictionnary.cfg
Sending 'dictionnary.cfg' (1.0 MB)
Code is: 5677-fuel-venice-plato
On the other computer run

croc 5677-fuel-venice-plato

dominique@dominique-AcerAspire:~$ croc 5677-fuel-venice-plato
securing channel...2024/01/10 16:07:49 room not ready

[schollz]

very strange, lets keep this open. I can't replicate it but maybe something will come up.

have you tried on any other pair of computers?

[Dominique63]

I tried on another machine. Unfortunately I have another error message:
connecting...2024/01/11 11:24:18 could not connect to 5.161.69.143:9009: comm.NewConnection failed: dial tcp 5.161.69.143:9009: i/o timeout
So I didn't insist.
I specify that I test sending AND receiving on the same computer.

v9.6.17 also has this error, default and self hosted
