Getting "unusual activity for your account" (BadRequest) when deploying models on Azure for Students

Falha ao criar uma implantaçãoOur system has detected this request as unusual activity for your account. If you are confident this is in error, please contact support.

I'm unable to deploy LLM models in my Azure OpenAI resource through the Azure portal or the Foundry portal. I suspect a quota or rate limit restriction, but I can't confirm it, and I have no Microsoft support plan to escalate.

Environment

• Resource type: Azure OpenAI (API kind: OpenAI), pricing tier Standard (S0)
• Resource: weave-openai-se… (name truncated in the portal)
• Foundry project: weave-projects
• Region: East US 2
• Resource group: rg-weave-prod
• Subscription: Azure for Students
• Subscription ID: e863ed46-46f0-476f-874a-f406c6b7ea34
• Tenant ID: da49a844-e2e3-40af-86a6-c3819d704f49
• My role: Owner (full access)
• Public network access: Enabled
• Resource status: Active

And…

• When I try to deploy GPT 5 and 6 with Standard / Global Standard, the deployment fails with: "Error to deploy this model".
• In the Azure portal, the resource page also shows: "Could not connect to required services" (usually attributed to network, firewall, proxy, VPN or browser extensions). It happens on mobile 5G, with no VPN or ad blocker. Environment
