Unable to login to Omron Connect with API v2

[tomasancz]

I am able to login to Garmin Connect, but no way to Omron Connect.
I guess it's related to API v2. (Region EU: Czech Republic)

I tried for country code also US or GB (EU not accepted). Also tried to reset password for Omron connect to a simplier one to avoid typos, but no success :-(

I've tried an old test account from Ireland and it's still working 🤷.
The country has to match the country you've selected when creating the account. Checking older issues, there is at least one user from IT who has no problems either.

Hm I get the exact same result as @tomasancz when I tried. I wonder if there is more than one endpoint used in Eu?

I’ve just created a new account using CZ as the country on an iPhone and was still able to log in without any problems. I have no clue what could be wrong.

Me on the other hand after reading the reply I created a new account using 'IE' country code and wasn't able to log in with that one either.
I was executing it on Windows 10 in Power Shell
OS: Windows 10 Pro, Version 22H2, Build Number 19045.6691
PSVersion: 5.1.19041.6691
Python 3.12.10

Meanwhile my main omron accound got suspended after multiple attempts.
I could provide some logs from from attempts with the other test account if you let me know how.

bah, OMRON implemented ssl pinning, can't intercept https on iOS anymore.
This is a stripped down OMRON login script. Without arg it uses the settings implemented in omramin, with arg android it uses settings found on android. Recent iOS app does use vlt-mobile-api.prd.eu.ohiomron.eu too, that much I can tell without https sniffing.
For me both work fine.
