I've been dealing with a frustrating issue regarding Autopilot deployment failures since just before Valentine's Day. The deployment fails during pre-provisioning and throws an error message: "Something went wrong and we weren't able to install the enrollment status policy provider. Error: 0x800705b4." This happens after the "Preparing your device for mobile management..." step hits a 30-minute timeout. Generally, this step takes only a couple of minutes when successful, but now it's inconsistent, leading to wasted time and a backlog of laptops that need to be set up. We've used the same deployment profile over 200 times with very few problems, mostly on new computers, and nothing has changed on the Tenant side—no new apps or policies. It even failed on a Lenovo laptop that was recently imaged successfully. We're Entra joined and had previously made some network exceptions for Azure Front Door subnets, but there are no signs that anything is being blocked. I even tested a new laptop at home—failed twice before succeeding on the third attempt. Any thoughts or suggestions to resolve this would be greatly appreciated as we need to roll out about a dozen laptops quickly!

Autopilot seems to be working fine on my end. You might want to check out this article; it addresses a similar situation, especially with the "haven't changed anything in months" part. Here’s the link: call4cloud.nl/the-0x800705b4-error-in-our-stars/
I can’t offer much help, but I haven’t encountered any problems lately. In fact, it’s been weeks since I’ve seen a random Autopilot failure. We only provision or re-provision about 1-10 devices a week. Have you tried creating a new, simplified Autopilot profile to see if that helps? You could also use port mirroring to capture the traffic during Autopilot to make sure those new firewall rules are working properly.
Just curious, what version of the Intune Connector are you using? If it’s before 6.2501.x.x, that might be an issue. But since you're Entra joining, I guess that’s not applicable here.
They’re Entra joining, no connector.
Well, at least our Autopilot enrollment script is still functioning. We were lucky to test it out since this last laptop batch wasn't pre-enrolled into our Tenant as usual.

This may be a good lead, thank you!
