用户从法国赴华后无法登录Salesforce 寻求技术协助

Hey there, let's work through this Salesforce login issue since the initial network adjustments didn't resolve it. Here's a structured breakdown of troubleshooting steps to narrow down the problem:

Basic Checks to Start With #

• Double-Check Network Access IP Rules
  Even if you added China IP segments, there might be conflicting deny rules or your dynamic public IP might fall outside the range you configured. Head to Setup > Security > Network Access and verify:

  • The exact public IP your device is using in China is explicitly allowed (use an IP lookup tool to get this)
  • No deny entries are overriding your allow list

• Validate Geolocation & Session Restrictions
  Some orgs enforce geographic login limits alongside IP rules. Navigate to Setup > Security > Session Settings and check:

  • If "Restrict login based on geographic location" is enabled, confirm China is in the allowed regions
  • Session timeout or IP switching restrictions aren't blocking your login attempt

• Test Direct Salesforce Login
  Corporate SSO or branded domains might have their own restrictions. Try logging in directly via https://login.salesforce.com instead of your company's custom login page. If this works, the issue likely lies with your SSO provider's IP allowlist, not Salesforce itself.

Intermediate Fixes #

• Whitelist Salesforce Endpoints in Network Firewalls
  Local Chinese ISPs or company proxies might block critical Salesforce domains. Ensure these are whitelisted:

  • *.salesforce.com
  • *.force.com
  • *.salesforceliveagent.com (if your team uses live support tools)
    Test with a wired connection to rule out wireless network interference.

• Reset Browser State
  Cached credentials, VPN extensions, or ad blockers can cause login conflicts. Try:

  • Clearing browser cache and cookies
  • Logging in using incognito/private mode
  • Disabling browser extensions one by one to identify the culprit

• Verify MFA Functionality
  If your org uses Multi-Factor Authentication, confirm your MFA method works in China:

  • Ensure your authenticator app has stable internet access to sync time (MFA codes rely on accurate clock sync)
  • Try switching to a different MFA method (e.g., SMS if available) if the app isn't working

Advanced Troubleshooting #

• Check Salesforce Trust Status
  Confirm there are no ongoing outages or regional restrictions affecting China. You can access Salesforce Trust without logging in—look for the Asia-Pacific region status to see if there are any reported issues.

• Escalate to Salesforce Support
  If all steps fail, reach out to Salesforce Support with these details:

  • Exact error message or screenshot of the login failure
  • Your current public IP address in China
  • The IP segments you added to Network Access
    They can audit org-level restrictions or regional blocks that might be preventing access.
