Cannot connect to host my.porsche.com:443

[sracing]

I am using pyporscheconnectapi since a few month in a smarthome application (SmarthomeNG). So far, everything worked well and I pulled fresh data every 10 minutes. Since a few days, I am experiencing more and more connection issues.

My script to test the connection:

import asyncio
from pyporscheconnectapi.connection import Connection

email = "my@adress.de"
password = "mypassword"

async def vehicles():
    conn = Connection(email, password)

    data = await conn.get("https://api.porsche.com/service-vehicle/se/sv_SE/vehicle-data/WP0ZZZxxxxxxxxxxxxx/stored")

    await conn.close()
    return data

loop = asyncio.get_event_loop()
result = loop.run_until_complete(vehicles())

print(result)

The error message:

As said, I believe the issue did not come up instantly, I more had the impreesion it came up more and more over the last days. Now approx. 95% of the connections fail.

Is it just me having those issues?
Anything I can do in my script to solve this?

Any support or feedback is appreciated.

Since 2022-07-01 // 03:00 am there is stable connection again without having changed anything on my side. Seems the root cause was on the Porsche Server side for several days.
