I can't implement LLM models in Azure Foundry due to rate limit blocking or something similar (I've done everything and I don't have Microsoft 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
