The VRM API documentation says that 429 ("Too many requests") responses should provide a Retry-After header specifying how many seconds to wait before trying again (https://docs.victronenergy.com/vrmapi/overview.html#rate-limiting-and-error-429) but in our testing we haven't seen that header appear. Should there be a Retry-After header with a 429 response, or is the documentation off?
Also, a colleague of mine tried to create an account on this forum today to ask this question and was unable to; when he submits the "create account" form, it asks him to "please correct the error on the page" or something like that, but no error is highlighted. Are there any known issues with account creation?
