Hello everyone,
I have a problem when I try to connect web2py to a mysql database.
I'm using a Debian 9 strech, Web2py 2.18.3-stable +
timestamp.2019.03.03.23.22.30 (Running on Apache / 2.4.25, Python 2.7.13)
and mysql 8.0.15.
I don't have any problem when I use storage.sqlite.
But when I try to migrate on Mysql, I always have the same error:

81.23.32.9.2019-03-05.13-55-17.e8fb714e-4e1d-4e5c-8502-a36374e00a23

I use the following syntax:
'mysql://user:passwd@localhost/gmao?set_encoding=utf8mb4'
I also notice this error message when I try to replace storage.sqlite by
mysql :
An error occured, please <a
href="/admin/default/edit/welcome/models/db.py?id=models__db__py">reload</a>
the page
I have the same error when I try to modify this in appconfig.ini.
Thank you all in advance for your help.
