TLS Error: incoming packet authentication failed from [AF_INET6]::ffff:noip:36123

Good morning, everyone.
I come back to try to understand an error when everything looks perfectly good. I configured a vpn connection using openvpn.
So I installed openvpn server on my windows server
I installed openvpn on my windows 10 client. The connection goes perfectly well, no problem.
So I convert my windows client configuration file to android client. And there, I have this error that appears: (and unable to connect to the server from this client)

Authenticate/Decrypt packet error: packet HMAC authentication failed

Does anyone have any idea?

HMAC authentication failed because the --tls-auth key is corrupt or wrong.

Maybe you have corrupted the key or file ? Like Line-endings ?

Finally, I started all over again. And by creating a specific ovpn folder in android with only config files, everything works perfectly. Thank you so much for your help
