[SOLVED] SMTP Error

Hello dear!
I'm planning to deploy appwrite for migration from firebase. I'm deploying appwrite in docker swarm. It seems to be starting, but I ran into a strange SMTP problem. Cant send invite..

appwrite-worker-mails log:
[Worker] Worker 0 is ready!
Worker mails started
[Job] Received Job (657ee8a6430838.07524580).
[Job] (657ee8a6430838.07524580) failed to run.
[Job] (657ee8a6430838.07524580) Error sending mail: SMTP Error: Could not authenticate.
[Error] Type: Exception
[Error] Message: Error sending mail: SMTP Error: Could not authenticate.
[Error] File: /usr/src/code/src/Appwrite/Platform/Workers/Mails.php
[Error] Line: 96

I tried different SMPT configurations in .env, different servers, but the answer is always the same. I can't connect to the servers.
Version Appwrite 1.4.13
.env:
_APP_ENV=production
_APP_LOGGING_CONFIG=
_APP_LOGGING_PROVIDER=
_APP_OPENSSL_KEY_V1=mypassword
_APP_REDIS_HOST=appwrite_redis
_APP_REDIS_PASS=
_APP_REDIS_PORT=6379
_APP_REDIS_USER=
_APP_SMTP_HOST=mail.mySMTPserver
_APP_SMTP_PASSWORD=myPasswordForSenderEmail
_APP_SMTP_PORT=25
_APP_SMTP_SECURE=
_APP_SMTP_USERNAME=SenderEmail@mySMTPserver
_APP_SYSTEM_EMAIL_ADDRESS=SenderEmail@mySMTPserver
_APP_SYSTEM_EMAIL_NAME=SenderEmail@mySMTPserver
_APP_SYSTEM_SECURITY_EMAIL_ADDRESS=SenderEmail@mySMTPserver
_APP_WORKER_PER_CORE=6

telnet on 25, 465, 587 ports connected

Have you double checked the same credentials with an email client?

Btw, it's best to use 3 back ticks with multi-line code. See https://www.markdownguide.org/extended-syntax/#syntax-highlighting

thx!
I checked configs with email clients, and found a problem in the smtp server
