Bing Map tiles are throwing SSL/TLS error intermittently.

Thanks Dev.

Will ask there.

Hi Vikas,

By "We are using Bing map in SSRS in native form" I assume you are using Directly accessing the Bing Maps tiles - Bing Maps | Microsoft Learn but failures will occur if you are not doing the metadata call for each session you have with the tile server (Get Imagery Metadata - Microsoft Bing Maps | Microsoft Learn). As the Microsoft Maps team updates tiles worldwide, the tile server changes and some tiles will be no longer available.

Sincerely,

Hi All,

Thanks for reply. We found the issues so thought to post here. May be helpful for others.

In SSRS, when we add any map layer, it calls dev.virtualearth.net (its native code in MS provided DLL under SSRS) to get the maps URLs(it is served via CDN like ecn.t?.tiles.virtualearth.net). Then SSRS makes the call to respective URL and gets the tiles of the map.

Issues was, we are using Windows 2022 server edition which by default enables TLS 1.3 and communication imitation from our end to Bing was on TLS 1.3. From Bing side it requests for TLS 1.2 and then protocol negotiation happens. Most of the calls went throw means negotiations are fine and handshake happens properly but for some of the packets it turns to be in Illegal Parameter (47) error and those packets turns us the SSL/TLS error on the Tiles.

We reached to MSFT, and they are investigating it but for now we have disabled the TLS 1.3 in client key of registry i.e., while starting the connection go with TLS 1.2 instead of 1.3, kind of fixed the issue and no more errors coming.

This might not a perm fix but for us it worked as of now.

With Regards,
