Due to the number of affected regions, the rollout may take some time to propagate across all environments. Applications should gradually regain full file storage access as the fix is applied to each region. Existing files and data remain unaffected. Next update: We will provide another update once the rollout is complete.

We are investigating an incident with Mendix deployments across all regions. Customers may experience application startup failures and deployment errors when their application model contains log nodes with special characters (quotes, umlauts, or non-ASCII characters). Customers can temporarily resolve the problem by renaming log nodes in Mendix Studio Pro to use only ASCII characters (A-Z, a-z, 0-9, underscore, hyphen, space) and redeploying. This incident will be updated as events warrant.

Notice February 6, 2026

Mendix Cloud EU (Frankfurt) issue sending email using SMTP relay

Detected by Pingoru: Feb 06, 2026, 03:13 PM UTC
Resolved: Feb 24, 2026, 01:53 PM UTC
Duration: 17d 22h

Affected: Mendix Cloud EU (Frankfurt)

Timeline · 3 updates

identified Feb 06, 2026, 03:13 PM UTC

We have identified an issue in the region Mendix Cloud EU (Frankfurt). Customers sending email, using an SMTP relay over port 25, might be unable to deliver those e-mails. This issue is caused by one or more of our outgoing IP addresses being blocklisted by an external email security provider. We are in communication with the external email security provider to have the affected IP addresses removed from their list. Until then, our advice is to switch to a different SMTP relay provider and avoid using port 25 for sending email altogether.
identified Feb 11, 2026, 12:15 PM UTC

We are continuing to work on a solution for this issue.
resolved Feb 24, 2026, 01:53 PM UTC

This incident has been resolved. The affected outgoing IP addresses have been removed from the external email security provider's blocklist. Email delivery via SMTP relay from Mendix Cloud EU (Frankfurt) is operating normally again. As a general best practice, we recommend using port 587 (TLS) instead of port 25 for outgoing email. Please refer to our Sending Email documentation for recommended SMTP configuration: https://docs.mendix.com/developerportal/deploy/sending-email/#external-email-providers
