Ошибка вызова sspi mysql - Не ошибается лишь тот, кто ничего не делает!

I hope this is not too vague of a question, but I have looked far and wide but have not been able to find anything helpful for this error.

I have a .NET 4.5.2 web service tier (using ServiceStack & Dapper) that has been receiving these two errors infrequently ever since we deployed the service.

The first error:

2017-09-29 18:13:26.637 +00:00 [Error] Class: "TokenRepository" | Method: "GetToken"

A little background on my stack:

.NET 4.5.2
Dapper 1.50.2.0
ServiceStack 4.5.4
MySQL 5.6 (using Amazon Aurora)

We do not receive this error in any other of our environments, which we are not running Aurora and simply just running MySQL 5.7.17 on Amazon RDS.

As I mentioned, these errors are sporadic and do not always happen on the same methods/services but they always happen when executing a SQL command using Dapper from the service tier to the MySQL database.

Is there anyway to debug this further or are there any known issues related to MySql/Aurora/Dapper? I have not been able to locate any after researching.

I’m trying to connect to our MySQL database via PBI Desktop (Version: 2.112.1161.0 64-bit (December 2022) using the MySQL connector. I’m able to make an intial connection but then get the «A call to SSPI failed, see inner exception» error. I’m able to access the server with no issues in MySQL Workbench using the same credentials. Searching the forom I found what appears to be a solution here: «A call to SSPI failed, see inner exception» -> HE… — Microsoft Power BI Community.

I’ve unchecked the Encrypt Connection option, clicked the OK button, then close. But….then what? If I go back to Get Data and select MySQL again, it’s forgotten I made that change and I get the SSPI failed error again. Is there something in File > Options and settings I need to enable/disable?

Seeing this error seemingly randomly (never been able to recreate):

Intermittent A call to SSPI failed, see inner exception, he message or signature supplied for verification has been altered

.net 4.5 connecting to MYSQL 5.7.21 on RDS.

Is this an issue on our end or on AWS’ end?

Надеюсь, это не слишком неопределенный вопрос, но я посмотрел далеко и широко, но не смог найти что-либо для этой ошибки.

У меня есть уровень веб-сервиса .NET 4.5.2 (с использованием ServiceStack и Dapper), который редко принимал эти две ошибки с тех пор, как мы развернули службу.

Первая ошибка:

Небольшой фон в моем стеке:

.NET 4.5.2
Dapper 1.50.2.0
ServiceStack 4.5.4
MySQL 5.6 (используя Amazon Aurora)

Мы не получаем эту ошибку в любой другой нашей среде, в которой мы не работаем с Aurora и просто запускаем MySQL 5.7.17 на Amazon RDS.

Как я уже упоминал, эти ошибки являются спорадическими и не всегда случаются с одними и теми же методами/услугами, но они всегда возникают при выполнении команды SQL с использованием Dapper из уровня сервиса в базу данных MySQL.

Нужно ли еще отлаживать это дальше или есть какие-то известные проблемы, связанные с MySql/Aurora/Dapper? Я не смог найти их после исследования.
