YES! You are right! a directory called amissl must be available in env: and also in envarc:
sorry, i forgott! Thanks for clarification
The IBrowse site has the same error.
For everyone who needs the work around, this is correct (tested for AOS3):
makedir env:amissl
setenv amissl/ssl_client_version tls1
copy env:amissl envarc:amissl
Just make sure that in IBrowse AmiSSL 2 and 3 are enabled.
