There is something wrong with CORSAllowedOrigins

[abelliumnt]

config.toml file

# A list of origins a cross-domain request can be executed from
# Default value '[]' disables cors support
# Use '["*"]' to allow any origin
cors_allowed_origins = "[]"

# A list of methods the client is allowed to use with cross-domain requests
cors_allowed_methods = "[HEAD GET POST]"

# A list of non simple headers the client is allowed to use with cross-domain requests
cors_allowed_headers = "[Origin Accept Content-Type X-Requested-With X-Server-Time]"

Load result:

It seems that the string array is not well supported by toml serializer. @hleb-albau

Besides, if you repeat to execute tendermint init on the same home, these following sections will be very large.

CORSAllowedOrigins
CORSAllowedMethods
CORSAllowedHeaders

What serializer are you using? [] are not forbidden in strings https://github.com/toml-lang/toml#user-content-string nor do they require escaping.

@HaoyangLiu try without quotes

cors_allowed_origins = []
cors_allowed_methods = [HEAD GET POST]
cors_allowed_headers = [Origin Accept Content-Type X-Requested-With X-Server-Time]

[abelliumnt]

cors_allowed_headers = "[Origin Accept Content-Type X-Requested-With X-Server-Time]"

@hleb-albau The above value is automatically generated by tendermint init

[hleb-albau]

cors_allowed_headers = "[Origin Accept Content-Type X-Requested-With X-Server-Time]"

@hleb-albau The above value is automatically generated by tendermint init

If it without quotes works for you, I will provide pr fixing init.

[hleb-albau]

yeah, already fixed by @melekes . I also fixed docs in https://github.com/tendermint/tendermint/pull/3013

[abelliumnt]

@hleb-albau Well done!

Thanks folks!
