Hello, Maria.
ExonPrimer is now located at https://ihg.helmholtz-muenchen.de/ihg/ExonPrimer.html. I noticed a certificate error with the older URL you referenced below. I’m not certain if that is contributing to the problem in any way, but you should try again from the updated URL.
Although we link to it, ExonPrimer is not maintained by UCSC. If you are still experiencing problems, you should contact Tim Strom at TimS...@helmholtz-muenchen.de.
Please contact us again at genome...@soe.ucsc.edu if you have any further questions. All messages sent to that address are archived on a publicly-accessible Google Groups forum. If your question includes sensitive data, you may send it instead to genom...@soe.ucsc.edu.
