I received the following message : “authentication failed: request to https://mydomain/public/api/v1/ping?v2=true failed, reason: unable to verify the first certificate”. Do you have an idea ? Thank you November 12, 2019 at 5:29 am #22502 Hillel CorenKeymaster How did you create the SSL cert? You may want to use letencrypt. November 18, 2019 at 4:38 pm #22565 alexkava85Participant Thanks for your answer. I used ssls.com to create my certificate. Is it necessary to use letsencrypt ? Thank You November 18, 2019 at 4:42 pm #22566 Hillel CorenKeymaster It may help… November 19, 2019 at 4:08 am #22574 alexkava85Participant I changed to letsencrypt but now I have this message : authentication failed: Got 404 calling GET https://mydomain.com/public/api/v1/ping?v2=true, expected 2xx. I searched on the forum but it seems that I’m using the latest version of InvoiceNinja (4.5.15). Do you have an idea ? Thanks This reply was modified 3 months, 1 week ago by alexkava85.

November 19, 2019 at 1:05 pm #22618 alexkava85Participant I just emailed the URL to the provided address. Thank you November 19, 2019 at 1:16 pm #22619 Hillel CorenKeymaster Thanks, I believe you need to remove /public from the URL November 19, 2019 at 1:21 pm #22620 alexkava85Participant Thank you, it works perfectly. November 19, 2019 at 1:21 pm #22621 Hillel CorenKeymaster Glad to hear it, thanks for the update!
