Hi, I created a clone of a production server running Debian 8 (originally based on Debian 7). I upgraded it to Debian 9 and then to Debian 10. I believe I've followed the necessary steps in the Perfect Server guide to ensure I have all the packages needed, and I went through configuration files to ensure they are all current. But when I run the ispconfig3_install/install/update.php script from the most recent version of ISPConfig, I receive errors: .... Configuring Dovecot Creating new DHParams file, this takes several minutes. Do not interrupt the script. 142+0 records in 142+0 records out 142 bytes copied, 0.000608347 s, 233 kB/s unable to load DH parameters 140050755384448:error:0D0680A8:asn1 encoding routines:asn1_check_tlen:wrong tag:../crypto/asn1/tasn_dec.c:1130: 140050755384448:error:0D07803A:asn1 encoding routines:asn1_item_embed_d2i:nested asn1 error:../crypto/asn1/tasn_dec.c:290:Type=DHparams .... Trying to fetch mails from this server results in errors in /var/log/mail.err: Mar 8 17:54:17 upgradetest-2-isp dovecot: imap-login: Error: Failed to initialize SSL server context: Can't load DH parameters: error:1408518A:SSL routines:ssl3_ctx_ctrl:dh key too small: user=<>, rip=**********, lip=**********, session=<cFRSk1ugf/klzX/N> I wonder if this is related to the following bug report: https://git.ispconfig.org/ispconfig/ispconfig3/issues/5340 But since it is marked as fixed, I must have done something wrong. I just can't figure out what. What can I do to resolve the problem ? - Thanks
SORRY! I realize I had the same problem just a short time ago and found the answer here: https://www.howtoforge.com/community/threads/dh-parameters-error-message-via-update-php.82690/
