Unable to lift rate-limit after registration

[Jones1066]

The problem

I've been using signal-cli-rest-api for more than a year. I've just cleaned up my docker environment and have done a clean install with v0.96 and started with an empty data folder and clean registration. I've started clean several times but I can't get past the rate limit. I've included the docker debug logs below with some redactions. I'm losing hair - can anyone suggest what I might be doing wrong?

Many thanks in advance,
Jeff

Can you please post the REST API command you are using to lift the rate limit restriction? Does it work if you temporarily switch to the normal mode?
