      @j-smutek Hmmm. I just stood up a docker instance, went through the setup wizard, logged in as the admin user and created an API key on this screen:

      Screenshot 2023-10-24 at 7.46.44 AM.png

      I was unable to recreate.

      Are you using docker from the install guide?

      What operating system are you on?

      Does this error prevent the API key from being created?

      What does your .env file look like?

              After disabling https, I was unable to login to webUI as i was redirected back to login screen

              Url after redirect:

                After clean install (removed containers, volumes and images).
                I can create api key.
                Here is current docker usage, is it possible that https increases memory requirements?
                What are actual system requirements? (512MB stated in doc is not enougth)

                  @j-smutek Hmm. 512 MB should be fine for typical usage.

                  Do you have a large number of applications or tenants or webhooks or keys or anything else? Or is this a pretty standard config?

                  I'm glad you were able to get the API key created. That is a weird error I've never seen before.

                    sorry about late reply.
                    No i have created 1 application, 1 tenant, 1 user and no webhooks, the rest is default.

                      @j-smutek Thanks for the response.

                      The only thing I can think of that seems different is the certificates, but I can't see how that would affect the creating of an API key.

                        @dan Hi,
                        I don't think its certificate.
                        When i have time, i'll test it with and without certificates and see how i goes.

                          Hi, after a long bit of working on this issue.
                          I am quite certain that it is caused by setting a valid certificate in the configuration.
                          It happens when you configure it directly in the fusionauth.properties file ssl. Everything appears to work, then you find out you cannot create or edit tenants, and other areas do not work randomly. I would just get at no response in the browser and then this buffer overflow in your logs.. I struggled for quite some time with this. Just writing here so if someone else comes to this point.. Just stop and install a reverse proxy problem solved.

                          I also think honestly fusionauth's quick guide should include setup with caddy and/or nginx with ssl certs. Really I think it would be best to remove ssl setings and force users to setup a reverse proxy as it is simple to do. But I see that you maybe want flexibility here. I have done this now with Caddy and it works flawlessly.

                          Thanks again for a great product though and great community support.
                          Authfusion is by far the easiest alternative to Indentity Server for .net and probably the easiest auth server I found.
