The problems people actually hit, and the first thing to try for each.
Registration
"This email is already registered." The address has been used. Find your status link in your inbox rather than filling the form in again. If you genuinely cannot, contact the secretariat with the address you used and they can look it up.
The form will not move to the next step. A field on the current step is invalid. The offending field is highlighted and focused. The most commonly missed one is the undertaking tick on step 5.
The institution field is locked. The DTU student switch is on. Turn it off to type your own institution.
It says registration is closed. It is. Registration is a switch the secretariat controls; there is no queue and nothing to wait on the page for. The closed page shows their message about what happens next.
It wants a partner and I do not have one. Your first-choice committee is double delegation, which cannot be entered alone. Pick a different first choice, or find a partner.
Emails
Nothing has arrived. Check spam. Then check your status page, which shows the real state regardless of email. If the state is right, you have simply lost an email and staff can resend it. If you used a college address, that is the usual culprit.
The magic link says it is invalid or expired. They are single use and time limited. Request a fresh one.
Signing in
My password does not work.
You probably never set one, because you signed up with a magic link. Use the magic
link tab, then set a password at /account.
"Too many requests". Rate limited: ten sign-in attempts per ten minutes, five magic links per fifteen minutes, five signups per hour. Waiting is the only fix; retrying extends it.
I signed in but my dashboard says no registration found. Your account email and your registration email are different addresses. See your dashboard.
Allotment
I have been Registered for two weeks. Allotment is done by hand and takes as long as it takes. This is normal. Chase the secretariat only if a published allotment date has passed.
I got a portfolio I did not ask for. Preferences are requests, not reservations. Popular seats run out. Ask the secretariat if a swap is possible; they can revoke and re-allot, though it is deliberately an admin-level action.
Payment
The money left my account but my status has not changed. Do not pay again. If you paid by UPI or a static link, confirmation is manual and can take a day or two. Contact the secretariat with your transaction reference.
The payment page says payment is not configured. The secretariat has not finished setting up the provider. Nothing is wrong on your side. Tell them.
The page says there is no payment for me yet. Your token is valid but no payment has been raised, usually because you are not allotted yet, or because this is a free event with no payment step at all.
I paid twice. Contact the secretariat with both transaction references. Refunds are handled by them, under whatever policy is shown on the payment page.
Conference day
There is no QR code on my status page.
It only appears once you are CONFIRMED. If you are still on Payment sent, your
payment has not been recorded.
My phone is dead. Staff can find you by name or email at the desk. Bring ID.
Who to contact
The secretariat's contact addresses are on the conference homepage under contacts, and on your payment page. Include your full name and the email you registered with; it makes finding your record instant rather than a search.
