More detail
Safety first: reach the portal only through KRA’s own official site, and be wary of any link that arrives by text or email claiming to be eTIMS, since fake KRA pages are used to steal PINs and passwords. When in doubt, go to the official KRA website directly and find eTIMS from there.
If the genuine portal will not open, check that other websites load on the same connection. If they do and the KRA page still will not, the service may be briefly down or under load, in which case waiting and retrying is the fix. A business set up on an eTIMS-ready point of sale like Veira keeps issuing invoices through the app and is not dependent on the portal loading for every sale.
