command 'rpc_payments' produces 'Error: Unsuccessful -- json_rpc_request:'

[shermand100]

Monero v0.16.0

I cannot find a condition where the 'rpc_payments' command works.

####Starting the node with

./monerod --rpc-bind-ip=0.0.0.0 --rpc-bind-port=18083 --rpc-restricted-bind-port=18089 --confirm-external-bind --rpc-payment-allow-free-loopback --rpc-ssl disabled --rpc-payment-address=43HoAhqx9q3MR1crAjpQtYVhvzQhZgqPwSWVQMmPvYmr18qVUEjCHcsEasuCxS486rWSSg1gbGqanet67NWRsh1bQL9KkB9 --rpc-payment-credits=5 --rpc-payment-difficulty=100 --log-level=3

Allows free usage for local status, version, print_cn commands which output as expected. however rpc_payments fails with Error: Unsuccessful -- json_rpc_request: when requested in the same condition as the successful outputs.

The node can see the rpc request and gives a very limited log entry of:

2020-06-04 05:59:44.266 I HTTP [192.168.1.132] POST /json_rpc
2020-06-04 05:59:44.266 I [192.168.1.132:46638 INC] Calling RPC method rpc_access_data

####Further experimenting:

Starting the node with a more basic:

./monerod --rpc-bind-ip=0.0.0.0 --rpc-bind-port=18083 --confirm-external-bind --rpc-ssl disabled

Gives the same result. Successful output of all status commands except rpc_payments so I can't pin it onto a particular start flag.

####Other attempts at finding clues:

But I'm don't think any of that helps.

####Duplication of error

Another user seems to have this problem

https://www.reddit.com/r/monerosupport/comments/gvucdk/how_to_start_daemon_with_rpc_pay_and_local_free/

Although he/she may be using my same or similar start command so user error is still a possibility!

Any help appreciated, or I can try to produce a more helpful log if you direct me how.

The request goes to the default server, the unrestricted one, which does not have payments enabled. It's kind of a longstanding problem that we have two RPC servers when using --restricted-rpc-port.

[pvols1979]

Is there a command-line option to specify a port so that we specifically request from the restricted RPC port? Something like './monerod -port 18089 rpc_payments'

[pvols1979]

When I first started running my node after the RPC-Pay feature was added, I ran in interactive mode without detaching. This worked excellently. I would use Screen and swap over to the active session whenever I wanted to run commands against the daemon. However, rpc_payments was always such a huge return as far as output lines that I could not see every line. I thought it would be nice to output the return of the list to less or more, but I was unable because I was at the server command line and not the bash prompt. So, this new feature allowing me to run a restricted and non-restricted port is perfect, I just need this command to work as well as the commands listed above.

[moneromooo-monero]

Not yet. Worth adding.

[moneromooo-monero]

Oh, and that won't help for this case, since the unrestricted server will have pretty much no activity on it, so its RPC data will be mostly empty, wihch is not what you wanted (you wanted the data from the restricted server).

[pvols1979]

Yes. That is correct. I want the data from the restricted server.

The RPC allow free loopback introduced in late has v0.16.x.x fixed this issue.

Example working RPC Pay run command for other that stumble across this (Allows local free status, but external RPC Pay):

./monerod --rpc-bind-ip=$DEVICE_IP --rpc-bind-port=$LOCAL_PORT_BEHIND_FIREWALL --rpc-restricted-bind-port=$RPCPAY_PORT_ACCESSIBLE_THROUGH_FIREWALL --confirm-external-bind --rpc-payment-allow-free-loopback --rpc-ssl disabled --rpc-payment-address=$PAYMENT_ADDRESS --rpc-payment-credits=$CREDITS --rpc-payment-difficulty=$DIFFICULTY --detach

@shermand100 I am still getting the same error:
