How this failure appears in Base44
Base44 is often used for prompt-built business apps, portals, and internal tools. With login problems, the builder may show a healthy preview while the published domain, another user role, a refreshed session, or a connected service reveals the real failure.
Why the obvious AI fix may miss it
platform data rules, generated workflows, integrations, and export boundaries can limit repairs when the project outgrows the builder. For this symptom, the investigation also considers cookie settings, callback URL mismatch, session persistence, authorization and row policies. Editing the visible component again will not help if that component is only reporting a failed request or policy decision.
The evidence that narrows the diagnosis
Useful first evidence includes try one clean test account; record the redirect chain; compare preview and production domains. For Base44, also identify whether the behavior differs between editor preview, shared preview, exported code, and the real production URL.
Safe access for a Base44 repair
A useful access plan may include builder access, workflow descriptions, data model details, screenshots, and export options. Start with names, URLs, logs, and screenshots. Do not put passwords, recovery codes, private API keys, or service-role credentials in the initial request.
What not to do before a repair
Do not disable authorization globally or share a real customer password. Preserve the last known-good Base44 version or export and avoid several broad prompt changes at once. That keeps the failure reproducible.
Repair inside Base44 or outside it?
Keep the repair in Base44 when its settings, workflows, code surface, and test tools expose the responsible layer. Export, source-code work, or a bounded migration becomes appropriate when the builder hides the cause, cannot support a safe implementation, or prevents repeatable production testing.
