Did you encounter 502 Bad Gateway while submitting your BTO application or SBF application?
A 502 Bad Gateway error means the web server you've connected to is acting as a proxy for relaying information from another server, but it has gotten a bad response from that other server.
Simple terms: You try to visit the webpage but one web server gets an invalid response from another.
Normally, the problem occurred especially the first day of BTO or SBF sale exercise. It is possible the server is overloaded or there are network issues between two servers. It is just a temporary problem.
So don't panic.
When applying your BTO or SBF applications, it is NEVER FIRST-COME-FIRST-SERVED BASIS. HDB will shortlist their BTO/SBF applications using a computer ballot.
No need to rush to submit. Just wait for few more hours then try again later or maybe apply the next day. Their BTO or SBF application are opened only for 7 days. Still got time. Don't need to KANCHIONG.
