Microsoft Business Central sign-in unavailable

Status Service Restored

Impacted services Dynamics 365 Business Central

Details Title: Users are experiencing failures when attempting to access your environment

User impact: Users were experiencing failures when attempting to access your environment.

Final Status: The redeployment has finished, and we have applied our configuration changes. After monitoring telemetry, we have confirmed that environment access has been restored.

A Post Incident Report will be published within five days.

Preliminary Root Cause: A portion of our database infrastructure responsible for environment accessibility had entered an unhealthy state.

Next Steps: We're analyzing performance data and trends on the affected systems to prevent this problem from happening again.

It appears that Microsoft has now restored access to the affected Dynamics 365 Business Central environments. Based on current telemetry and customer feedback, most users should be able to sign in again as normal.

If you are still experiencing issues, we recommend the following first step:

• Close your browser completely and reopen it, then try signing in again. This forces a refresh of the session and routing, and in most cases resolves remaining access problems.

We sincerely apologise for the disruption this incident has caused. We understand the impact on your daily operations and appreciate your patience while we worked in collaboration with Microsoft to stabilise the service.

Microsoft will publish a Root Cause Analysis (RCA) report as soon as it becomes available. Please note that this may take up to two weeks.

We will continue to monitor the situation closely. If any further issues occur, we will communicate immediately via this status page.

Microsoft has shared a new update regarding the ongoing issue with Dynamics 365 Business Central (Incident ID - DN1215469):

In addition to redeploying the affected infrastructure, they are now also implementing configuration changes to redirect traffic to redundant node infrastructure. These steps are part of their effort to restore full service availability. The next official update from Microsoft is expected at 17:00 CET.

We continue to monitor the situation closely and will keep you informed as soon as more details become available.

Microsoft has confirmed that the ongoing accessibility issues for Dynamics 365 Business Central are related to their Azure Front Door infrastructure. This means the impact is not limited to Boltrics customers, but affects all Business Central customers in the Benelux region.

We are in active discussions with Microsoft to resolve this as quickly as possible. Microsoft is currently working on restoring stability and availability across the affected Azure Front Door entry points.

A temporary workaround is available, but we strongly recommend applying this in consultation with your IT department, as it may require changes to network configuration and security policies.

Workaround (temporary):

If you are able to connect using a VPN (for example via the United States/Spain/Portugal), your connection will route through a different Azure Front Door location. Customers who can do this generally report the environment to be fast and stable via that route. We acknowledge that this is not an easy or ideal workaround, but at this moment it is the only known option to bypass the impacted Front Door endpoints.

We understand the operational impact this is causing and are doing everything we can together with Microsoft to get the service fully stable and operational again as soon as possible. We will continue to monitor the situation closely and provide updates as soon as more information becomes available.

Microsoft has officially acknowledged the issue affecting Dynamics 365 Business Central. According to their investigation, a portion of the database infrastructure responsible for environment accessibility has entered an unhealthy state. They are actively redeploying the impacted infrastructure and are monitoring telemetry to confirm recovery.

We will continue to monitor the situation and provide updates as soon as new information becomes available. The next update from Microsoft is expected on Thursday, January 8, 2026, at 13:00 CET.

Unfortunately, we are still seeing issues on some environments. While access had temporarily recovered for many users, some tenants are currently still affected and unable to sign in.

We have escalated the ticket with Microsoft again and are awaiting further updates. We will continue to monitor the situation closely and share more information as soon as possible.

We are seeing signs of recovery. All environments appear to be accessible again, and users are able to log in to Microsoft Business Central.

At this time, we are still awaiting official confirmation or feedback from Microsoft regarding the root cause. We will share their response as soon as it becomes available.

We have reported the issue to Microsoft and are currently awaiting their response. The problem appears to be on Microsoft's side and affects access to the Business Central sign-in page. We will share further updates as soon as more information becomes available.

Several customers are currently experiencing an issue where users are unable to sign in to Microsoft Business Central. Attempts to login result in a 504 Gateway Timeout error, indicating a disruption in the Microsoft platform.

The issue appears to originate from Microsoft's infrastructure (Azure Front Door), and we have reported it to Microsoft for further investigation.

We will provide an update as soon as more information becomes available.
