I did my Docker installation and accessed it, but it doesn’t appear to enter a login and password, but rather a message: The CMS is temporarily offline while an update is in progress. Check with your system administrator for updates or refresh your page within a few minutes. Then I saw that the table change should be done in the database:
ALTER TABLE oauth_clients CHARACTER SET utf8 COLLATE utf8_general_ci;
I did and my log was
MySQL [cms]> ALTER TABLE `oauth_clients` CHARACTER SET utf8 COLLATE utf8_general_ci;
Query OK, 0 rows affected, 2 warnings (0.450 sec)
Records: 0 Duplicates: 0 Warnings: 2 the table structure was: oauth_clients | CREATE TABLE `oauth_clients` (
`id` varchar(254) CHARACTER SET utf8mb3 COLLATE utf8mb3_general_ci NOT NULL,
`secret` varchar(254) CHARACTER SET utf8mb3 COLLATE utf8mb3_general_ci NOT NULL,
`name` varchar(254) CHARACTER SET utf8mb3 COLLATE utf8mb3_general_ci NOT NULL,

restart the cms-web container as well, but it continues with the same message, instead of the login screen
